# Quick Answer: What Is The Sum Of The Exterior Angle?

## What is the sum of the exterior angles of a Pentadecagon?

A pentadecagon in Geometry is any 15 sided, 15 angled polygon and the sum of its interior angles will always be 2340 degrees.

The name pentadecagon is derived from the names of smaller polygons.

Penta means five and is derived from the pentagon with five sides..

## Is the sum of exterior angles always 360?

Exterior angles of a polygon have several unique properties. The sum of exterior angles in a polygon is always equal to 360 degrees. Therefore, for all equiangular polygons, the measure of one exterior angle is equal to 360 divided by the number of sides in the polygon.

## What is the definition of exterior angles?

noun Geometry. an angle formed outside parallel lines by a third line that intersects them. an angle formed outside a polygon by one side and an extension of an adjacent side; the supplement of an interior angle of the polygon.

## How do you find the sum of exterior angles?

The sum of the exterior angles of a regular polygon will always equal 360 degrees. To find the value of a given exterior angle of a regular polygon, simply divide 360 by the number of sides or angles that the polygon has.

## What is the sum of exterior angle of Pentagon?

The exteriors angles of a pentagon are (m + 5)°, (2m + 3)°, (3m + 2)°, (4m + 1)° and (5m + 4)° respectively. Find the measure of each angle. Hints: The sum of all exterior angles of a polygon is 360°.

## What is the formula of exterior angles?

The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.

## What is the sum of the exterior angles of a hexagon?

The measure of each exterior angle of a regular hexagon is 60 degrees. The sum of the exterior angles of all regular polygons equal 360 degrees….

## What is the sum of the exterior angles of a 18 sided shape?

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 the exterior angles of a polygon with 100 sides?

360∘Since we know that sum of exterior angles of a convex polygon is 360∘ . so the sum of the exterior angle of the convex polygon with 100 sides is 360∘ .

## Why do all exterior angles equal 360?

When all of the angles of a convex polygon converge, or pushed together, they form one angle called a perigon angle, which measures 360 degrees. If the sides of the convex polygon are increased or decreased, the sum of all of the exterior angle is still 360 degrees.

## What is the sum of the exterior angles of any polygon?

Sal demonstrates how the the sum of the exterior angles of a convex polygon is 360 degrees.
