## What polygon has an exterior angle of 40?

1 Answer.

BRIAN M.

A regular polygon with exterior angles of 40o would have 9 side and be a nonagon..

## What is the measure of an exterior angle of a regular 40 Gon?

A regular polygon with an exterior angle measure of 40 degrees has nine sides. Every polygon’s exterior angle sum equals 360. So 360/40 equals nine.

## What is the exterior angle of a 10 sided polygon?

The regular, convex decagon is a subtle and elegant shape, with 10 exterior angles of 36° , 10 interior angles of 144° , and 10 vertices (intersections of sides).

## What is a 39 sided shape called?

## How do you find the exterior angle of a 15 sided polygon?

Since the sum of the exterior angles is always 360 degrees, if you divide 360 degrees by 24 degrees you get 15 which is the number of equal exterior angles and therefore 15 vertices and sides to the polygon.

## How many sides does a polygon with an exterior angle of 12 have?

30 sidesTherefore, dividing the number of degrees by number of angles (or sides) should yield the average number of degrees per angle. So, So, a regular polygon with an exterior angle measure of 12 degrees has 30 sides.

## How many sides does a polygon have if the exterior angle is 30?

12 sidesSince all the angles are congruent, 30a=360 , and a=12 . Since a=s , s=12 , so the polygon has 12 sides.

## 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 a 70 sided shape called?

heptacontagonIn geometry, a heptacontagon (or hebdomecontagon from Ancient Greek ἑβδομήκοντα, seventy) or 70-gon is a seventy-sided polygon. The sum of any heptacontagon’s interior angles is 12240 degrees.
