What is a 0 Sided Shape?

A zero sided shape technically isn't a shape. The definition of a shape is a closed figure with at least one points evenly going to another point. A circle is the figure with the least amount of sides because it has one side, which is considered the circumference of the circle.

How do you figure out the coordinates of the vortex are?

A vortex is a spinning or whirling mass of fluid: liquid or gas. Typical examples are a whirlpool or whirlwind or hurricane. These are extended shapes and do not have a single set of coordinates.

Where does the word 'cocktail' come from?

It is a slurred word for coquetier. It is said in the 1800's the word eventually became slurred to cocktail.

coquetier: A classic egg cup, the French word for which was once thought to be the origin, through mispronunciation, of the word "cocktail".

Where did the word honky come from?

There is a fairly lengthy discussion of this at http://www.phrases.org.uk/bulletin_board/13/messages/194.html.

What is the cosine 894?

cos(894 deg) = -0.9945, approx.

Where does the word libero come from?

The word 'libero' is Italian. It comes from the Italian word that means free because the libero can switch in and out to play defense without using substitutions.

How hard is trig?

Not Real Hard in My opinion all that you really have to do is remember Formulas

How do you change sine to degree?

You cannot. Sine is a ratio, degrees are a unit of measurement for angular displacement. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.

What are cartesian coordinates?

Cartesian coordinates are plotted on the Cartesian plane which consist of a horizontal x axis number line and a vertical y axis number line whereas both axes are perpendicular to each other and meet at right angles at the point of origin whose coordinates are at (0, 0)

If cosecA plus cotA equals 11by2 then find the value of tanA?

CosecA + CotA = 11/2

Cosec2A - Cot2A = 1 {By the Identity}

(CosecA + CotA) (CosecA - CotA) = 1

11/2 (CosecA - CotA) = 1

(1/SinA) - (CosA/SinA) =2/11

(1 - CosA) / SinA = 2/11

Therefore 1 - CosA = 2

CosA = 3 and SinA = 11Therefore TanA = SinA / CosA = 11/3

What are 26 facts and features about geometrical angles from A to Z?

Angles are measured in degrees, minutes and seconds

Base angles of an isosceles triangle are equal

Complementary angles add up to 90 degrees

Decagon is a 10 sided polygon whose inside angles add up to 1440 degrees

Exterior angles of any polygon add up to 360 degrees

F as a capital letter has equal corresponding angles

Greater than 0 but less than 90 is the measure of an acute angle

Hexagon is a 6 sided polygon whose interior angles add up to 720 degrees

Interior angles of any polygon: (n-2)*180 whereas 'n' is number of its sides

Joined line segments form angles at a point

K as a capital letter has angles that add up to 180 degrees on a straight line

L as a capital letter has a right angle

Measurements of angles can be done with a protractor

Nonagon is a 9 sided polygon whose interior angles amount to 1260 degrees

Obtuse angle is greater than 90 but less than 180 degrees

Perpendicular lines meet at right angles which is 90 degrees

Quarter of a turn is 90 degrees

Right angle triangle has a 90 degree angle and two acute angles

Supplementary angles add up to 180 degrees

Transversal line cutting through parallel lines creates various angles

Undecagon is an 11 sided polygon that has inside angles totalling 1620 degrees

Vertex is the point where two lines or more meet creating an angle

Whole turn is a complete revolution of 360 degrees

X as a capital letter has equal vertical opposite angles

Y as a capital letter has angles that add up to 360 degrees around a point

Z as a capital letter has equal alternate angles

What shape has seven side?

A seven sided shape is called a heptagon or a septagon.......

The inside dimensions of a removal lorry are 2.5m by 3m by 4m A pole vaulter's pole is 5.7m long Will it fit inside the lorry?

The pole will not fit: The diagonal of the side with edge lengths of 3 m and 4 m is 5 m, from the Pythagorean theorem. The diagonal of a triangle perpendicular to the first named diagonal is sq rt (52 + 2.52) = 5.59, slightly shorter than the vaulting pole.
