Why is the pentagon the shape of a pentagon not any outer shape in Washington DC?
The building plans was made for another site where it had to have that shape to maximize the use of the land. The building site was changed but the plans kept the old way since it was early war time (beginning of WW II) and the building had to be finished as soon as possible

add all of the triangle area in a pentagon to get area The area A of a regular polygon with n sides each s units long, perimeter p , and apothem a : A = ( ans )/2 or A = ( ap )/2.
The base of a pentagon is a straight line. In a regular pentagon, the two adjacent sides include obtuse angles of 108 degrees.
A pentagon is a 5 sided polygon whose 5 interior angles add up to 540 degrees.
Yes, it can be used to form a Dodecahedron. I don't see how! But cut out a pentagon from a piece of paper. Nextmake a fold along a line between any 2 corners which are not nextto each other. It's no longer 2D. . +++ . I am not sure what the second sentence is about, but each of the12 faces of a D…odecahedron is a regular Pentagon. . You can also make a pentagonal prism, of course: two pentagonalends joined by square or rectangular sides. (This is the basis ofthe prism in the viewfinder of a single-lens reflex - or SLR -camera.)

I'm actually having a hard time thinking of any myself. I hope someone else can. The main thing to remember is that pyramids, like cones, come to a point (or apex) at the top. So a Toblerone bar is *NOT* a pyramid. Rather, it is a triangular prism.

there are 35 triangles in a pentagon with a pentagram inside. We can see that there are seven different distinct types of triangles(you can cout them). Since you can rotate the triangle in five different ways we do 7*5 . do i knw u telephone by lady gaga. tik tok by k.
A pentagon shape looks like a house with the slanted roof and square bottom. It is a closed, plane, 5-sided figure with all straight sides. A regular pentagon has all 5 sides the same length. These are all pentagons.
Cut the carefully selected wood to the desired size. The wood used is either imported rosewood or ebony. . Shave the wood using a specially designed plain from the Edo period (1603-1867). The artist rotates and gently shears each chopstick countless number of times until it reaches a preferred st…ate. . Once a group of chopsticks are created, they are dampened and spun together to create a unified length. . With approximately seven chopsticks laid side-by-side in one hand, the craftsman polishes the chopsticks into their final shape. . The chopsticks are polished again and laid to dry naturally under the sun for 1 day. . A final polish and buff is applied, thus delivering a distinguished shine that helps to preserve the wood. With time, the chopstick will "age" gracefully and beautifully. (MORE)
A pentagon is a 2D, five sided shape. A regular pentagon looks a bit like a house, with a square without a top and instead a point.
There are multiple 3-d pentagon shapes. One such is theDodecahedron, it has 30 edges and 20 vertices. Another 3-d pentagonshape is the pentagonal prism.
A pentagon has five equal sides an octagon has eight equal sides. Look at a stop sign, that is an octagon, a hexagon has has six equal sides. Try google image search for examples. Draw a perfect five pointed star, with equal distant sides and angles, then connect the points of the star with lines, i…f it is a perfect drawing your star should now be surrounded by a five equal sided shape called a pentagon.

Well one to start off with is a house or even the pentagon [the top secret place] hope some of these helped.
It depends! If all its sides and angles are the same then it is a regular pentagon, however, if it's a five sided shape (5 straight sides that join to make a single shape), but it's sides or angles are not equal then it is an irregular pentagon.
to make any line you need two points.. so.. a pentagon has 5 vertices - ie. 5 points so how many ways can you select a combination of 2 - out of 5 points.. . 1,2,3,4,5 . (1,2) . (1,3 ) . (1,4 ) . (1,5 ) . (2, 3) . (2,4 ) . (2,5 ) . (3, 4) . (3, 5) . (4, 5) . so, there… you have it -> total of 10 ways :) -> so 10 diagonals. . now of course you could also think like this: ie. pose the question as follows how many ways can one select r number of goods from P number of total items: here in YOUR EXAMPLE: R =2 AND P =5 AND well, its a combination of r froma set of p -> which you are looking at: hence the answer = n c r = factorial n divided by factorial r = 5! / [2! x 3!] = = (5 X4X3X2X1) / (2x1).(3x2x1) = 5 x 2 = 10 Summarize now: you need a combination of 2 from a total of 5 .. and the formula is => factorial 5 - divided by factorial 3 divided by factorial 2 or mathematically expressed as n C r -> again, in your example, n = 5 [ pentagon] r = 2 [ you are looking for diagonals and it takes two to tango] . [ note: 2,1 is the same as 1,2 and 2,3 is the same as 3,2 and 2,4 is the same as.... etc etc ....] . cheers olga lednichenko (MORE)
No. A regular polygon has all sides the same length and all anglesthe same size. A regular pentagon has 5 angles each 108 degrees. Ahouse-shaped pentagon does not have all angles the same size, sotherefore it cannot be regular.

The sum of the interior angles of a pentagon is 540 degrees The Pentagon in Washington DC is named for its unusual shape a regular pentagon What is the measure of each angle of the Pentagon?
Okay, well the last guy obviously had no idea what he was talking about (MORON). Anyways, just divide the degrees, by the number of sides on a pentagon. Cheers! :D
A pentagon is a polygon -having five angles and five sides. ' Pente-' originates from Greek meaning five and -gon originates from the Greek word '-gonos' means angle .
The word pentagon describes a five-sided figure. The word is derived from the greek pente - which means five.
A pentagon is any five sided polygon. Its interior angles will add up to 540degrees
yes a pentagon is a rigid shape * * * * * I am afraid that it is not.
The Pentagon. A home plate. A House. A dog house. Stone's sign. School nerby road sign. Foundation sponge. A box
Yes, I do believe that no matter what shape it looks like, it is a pentagon if it has 5 sides.
hexagons work because each angle is 120 degress, as you say, and 3 times 120 equals 360 degrees. So three hexagons will surround a point with no 'space" left over. but the interior angle of a pentagon is108 degrees. three pentagons together only fill up 3 time 108, or 324 degrees. There is space le…ft over. But four pentagons would overlap. so 3 is not enough and 4 is too many. Pentagons cannot surround a point the way hexagons do. (MORE)
Two: a pentagonal base and 5 triangular faces. The triangles need not all be the same and if you count them as different shapes, there will be six shapes in all.
A pentagon is a 2-D shape. There is a 3-D shape with 12 faces, each a regular pentagon. It's called a dodecahedron. To make one out of (stiff) paper, you would cut out a "net", then fold and glue the edges. See related link for an illustration of a net you could print out.
Pentagons shaped like houses indicate a school zone. Such signs are usually a neon yellow-green. Pentagons that are not shaped like houses and are blue and yellow indicate a county route. Such signs are commonly found in states like New Jersey, New York, Florida, California and many others.
A pentagon is a 5-sided polygon. A regular pentagon has all sides of equal length and all interior angles are equal, each measures 108Â°.
The Architect was George Bergstrom and the General Coontractor was John McShain. Colonel Leslie Groves was the Army representative on the project. (The same Groves who also organized the Manhattan Project for the Army).
As a target it could hardly be overlooked. It routinely houses as many as 25,000 military and civilian workers.
the original answer was : It represents the US. military's five branches of service: Army, Marines, Navy, Air Force and the Coast Guard. This can't possibly be true, the Air Force was establish in 1947. The Pentagon was built in 1943. ?
A hexagon is a 6-sided figure, while a pentagon is a 5-sided figure. A school crossing sign in the United States is a pentagon. In many cases, hexagons and pentagons have sides that are all the same length, although this is not required.
A pentagon is a five sided regular polygon; as such, it is made up of five line segments. If you wanted to, you could also construct a pentagon out of five triangles that fit together much like a pie.The shapes that make a pentagon is triangles, rhombuses and diamonds.

The base of a pentagonal prism is a pentagon. Just like a square pyramid has a square for a base, a pentagonal prism has a pentagon for a base.
A pentagonal shape has 5 faces. For determining the name of a shape, it is determined by the amount of faces. For determining the amount of faces on a shape, it is determined by the pre fix of a word. tri-3 quad-4 pent-5. hex-6 hept-7 oct-8 non-9 deca-10 and so on.
A general pentagon may have no symmetries at all. A regular pentagon has five symmetry axes - each one connecting a vertex with the middle of the edge opposite this vertex. A regular pentagon also has rotational symmetry - if you rotate it by any multiple of 72 degrees clockwise or anti-clockwise yo…u get a regular pentagon as well. Please also see the related link below. (MORE)
The British 50 Pence coin is "heptagonal" in shape, ie. seven sided. (If it were pentagonal, it would have five sides.) The Royal Mint, as do many other mints around the world, produce some coins with different shapes as an aid to the vision impaired.
A pentagon is a 2-dimensional shape and therefore has no volume whatsoever. As a result, the formula is very simple: Volume = 0 units
Regular just means all the angles are the same size. A pentagon can be regular but it need not be.
A 5 sided shape is called a pentagon because Geometry was studied(and practically invented) by the Greeks. The word pentagon is madeup of two Greek words: ÏÎÎ½ÏÎµ Î³ÏÎ½Î¯Î± which are: ÏÎÎ½ÏÎµ (or pente) the Greek for 5 Î³ÏÎ½Î¯Î± (or gonia) the Greek f…or Corner or Angle. Thus the word "Pentagon" literally means "five angles", so apentagon is a shape with five angles. Having five angles it alsohas five sides. All two dimensional shapes are called polygons; this too comes fromtwo Greek words: ÏÎ¿Î»Î»Î¿Î¯ (polloi) meaning Many (transliterated into English as"poly") Î³ÏÎ½Î¯Î± (gonia) meaning Angle (as before). Thus a "Polygon" is literally a "many angled" shape. (MORE)
No, a pentagon has 5 sides. A four sided shape is called a quadrilateral. An example of a four sided shape is a square or a rectangle. However, there are also other four sided shaped like trapeziums and kites...
It depends on what you mean by a 3-d pentagon. To most people, a 3-d pentagon is a dodecahedron - a 3d shape with 12 pentagonal faces. In that case, each of the faces, by definition, must be a pentagon! If you mean a pentahedron - a 3d shape with 5 plane faces, it could be a triangular prism or a …quadrilateral based pyramid. In the first cae the bases are triangles, in the second, a quadrilateral. (MORE)
The base is a pentagon. It has five isosceles triangles rising from the sides to a point above it.
"What other" shape implies that there is at least one shape that you know of. But you have chosen not to share that information. Therefore I cannot be sure that my answer refers to another shape.
When a figure has 5 sides it is considered a pentagon. When a figure has 5 sides AND all the interior angles are 108 degrees then it is a regular pentagon.
It's not - it's actually a rectangle, with one corner cut off to prevent it being inserted into the phone incorrectly. It's called 'polarizing'.
A regular pentagon will have 5 equal sifes and 5 equal angles of 108 degrees.
A regular 5 sided pentagon has 5 equal sides and 5 equal interior angles that add up to 540 degrees
