# How do you make pentagon shape chopstick?

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)

# How many diagnals in a pentagon shape?

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 ....] .

# What shape can tessellate with a regular pentagon?

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)

A 5 sided shape is called a pentagon because Geometry was studied(and practically invented) by the Greeks.

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).
