# Quick Answer: What Is The Exterior Angle Of A 15 Sided Polygon?

## What is the interior angle of a 16 sided polygon?

Measurements.

Each angle of a regular hexadecagon is 157.5 degrees, and the total angle measure of any hexadecagon is 2520 degrees..

## 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 shape has an exterior angle of 15?

regular icositetragonThe regular icositetragon is represented by Schläfli symbol {24} and can also be constructed as a truncated dodecagon, t{12}, or a twice-truncated hexagon, tt{6}, or thrice-truncated triangle, ttt{3}. One interior angle in a regular icositetragon is 165°, meaning that one exterior angle would be 15°.

## What is the exterior angle of a 30 sided polygon?

So, for your 30-gon, the interior angles total up to (30-2) * 180 = 5040. Each interior angle is that total divided by the number of interior angles, or 5040/30 = 168º: The measure of each exterior angle is the total divided by the number of angles, or 360/30 = 12º.

## What is the exterior angle of a 12 sided polygon?

Explanation: For a regular n -gon, the measure of an exterior angle is 360˚n . Since a dodecagon has 12 sides, an exterior angles is 360˚12=30˚ .

## What is a 19 sided shape called?

EnneadecagonIn geometry an enneadecagon or enneakaidecagon or 19-gon is a nineteen-sided polygon.

## What’s a 99 sided shape called?

Polygons with 21 to 99 sides have a different system. Take the prefix for the tens digit (found on the left column), the ones digit (right column below), and then stick a “kai” between them to get (tens)kai(ones)gon . The 3-digit sided polygons are named in a similar fashion. A 100-sided polygon is called a hectogon.

## What is an exterior angle of a polygon?

An exterior angle of a polygon is an angle at a vertex of the polygon, outside the polygon, formed by one side and the extension of an adjacent side. … Exterior angles of a regular polygon are equal in measure. The magnitude of an angle can be determined by the number of sides of the polygon.

## What is the exterior angle of a 18 sided polygon?

He shows the formula to find it which is 360/n, where n is the number of sides of the regular polygon. He goes on further to explain the formula by taking an 18-sided regular polygon as example and computes its exterior angle as 360/18, which is 20 degrees.

## What is the sum of a 16 sided polygon?

So the sum of all of the measures of the interior angles of a 16-sided polygon is 2520 degrees.

## How many triangles are in a 16 Gon?

14 trianglesMaths keeps one mentally active. A 16-sided polygon has 14 triangles formed by joining one vertex to all the remaining vertices.

## What is a 1000000 sided shape called?
