How do you find the interior angle of a polygon

How do you find the interior angle of a regular polygon?

A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n – 2) * 180. To find the measure of one interior angle , we take that formula and divide by the number of sides n: (n – 2) * 180 / n.

How do you find the interior angle?

To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal.

What is the interior angle of a polygon?

The interior angles of a polygon are those angles at each vertex that are on the inside of the polygon . There is one per vertex. So for a polygon with N sides, there are N vertices and N interior angles . Notice that for any given number of sides, all the interior angles are the same.

What is the interior of a polygon?

Interior Angle (of a Polygon ) An interior angle of a polygon is an angle inside a polygon at a vertex of the polygon . Interior 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 formula for a regular polygon?

You also learned the formula for finding the area of any regular polygon if you know the length of one side and the apothem : A = (n × s × a)2 A = ( n × s × a ) 2 , where n is the number of sides, s is the length of one side, and a is the apothem .
