## What is a 100 sided shape?

hectogonIn geometry, a hectogon or hecatontagon or 100-gon is a hundred-sided polygon.

The sum of all hectogon’s interior angles are 17640 degrees..

## What is angle of Pentagon?

Internal angle (degrees) 108° (if equiangular, including regular) In geometry, a pentagon (from the Greek πέντε pente and γωνία gonia, meaning five and angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting.

## What is 7 sided polygon called?

heptagonA six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides… The names of polygons are derived from the prefixes of ancient Greek numbers. The Greek numerical prefix occurs in many names of everyday objects and concepts.

## What is 12 sided shape called?

dodecagonIn geometry, a dodecagon or 12-gon is any twelve-sided polygon.

## What’s a 13 sided shape called?

tridecagonIn geometry, a tridecagon or triskaidecagon or 13-gon is a thirteen-sided polygon.

## What is the angle of a 9 sided polygon?

140 °To find the value of an internal angle within this polygon, we can just multiply the number of triangles by 180 ° , then divide by the number of internal angles, which is nine. Excellent! So the interior angle of a 9 -sided polygon is 140 ° .

## What are the angles of a 10 sided polygon?

A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144° and they all add up to 1,440° . An irregular decagon has sides and angles that are not all equal or congruent.

## What is a 10 sided shape?

In geometry, a decagon is a ten-sided polygon or 10-gon.

## What is the angle in an octagon?

To find the measure of the angles, we know that the sum of all the angles is 1080 degrees (from above)… And there are eight angles… So, the measure of the interior angle of a regular octagon is 135 degrees.

## What is a 9 sided shape called?

enneagonIn geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.
