Question

What is the angle measurement of each interior angle?

Answer 1

Direct answer,

S=(n−2)180°

Short hand uses,

S=Sum

N=Number of sides

Example,

If you want to know the sum of the angles inside this figure, use the value n=8 in the formula.

S = (8 - 2)×180,

S = (6)×180,

S = 1080°

The sum of all of the interior angles of an octagon is 1080 degrees.

Answer 2

Answer:

The measure of interior angle of regular polygon = (n-2)180⁰ where n= the number of sides.

For example, measure of interior angle of a regular pentagon= ( 5-2)180⁰=540⁰.

(Where 5= the number of sides in a pentagon )
