#### What is the interior angle of a regular octagon

## How do you find the interior angle of a regular octagon?

Since an octagon has eight sides, subtract two from eight to get six. Multiply six by 180 to find the total number of degrees in an octagon equals 1,080. Divide 1,080 by eight to find the measure of each interior angle if the octagon is regular . In a regular octagon , each angle measures 135 degrees.

## What is the interior angle of a regular 20 sided polygon?

3240 degrees

## What is the interior angle of a regular?

All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides. The sum of exterior angles of a polygon is 360°.

## What is the interior angle of a regular polygon?

Angles . degrees, with the sum of the exterior angles equal to 360 degrees or 2π radians or one full turn. As the number of sides, n approaches infinity, the internal angle approaches 180 degrees. For a regular polygon with 10,000 sides (a myriagon) the internal angle is 179.964°.

## What is the formula for interior angles?

An interior angle is located within the boundary of a polygon. The sum of all of the interior angles can be found using the formula S = (n – 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.

## Does a octagon have 8 angles?

In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, ” eight angles “) is an eight -sided polygon or 8 -gon. A regular octagon has Schläfli symbol { 8 } and can also be constructed as a quasiregular truncated square, t{4}, which alternates two types of edges. A truncated octagon , t{ 8 } is a hexadecagon, {16}.
