Interior angles of polygons. In convex polygons each interior angle is always less than 180º some interior angles are well known and or easy to find. An exterior angle of a polygon is an angle outside the polygon formed by one of its sides and the extension of an adjacent side. If it is a regular polygon all sides are equal all angles are equal shape sides sum of interior angles shape each angle.

A polygon with three sides has 3 interior angles a polygon with four sides has 4 interior angles and so on. The angle next to an interior angle formed by extending the side of the polygon is the exterior angle. For a regular polygon by definition all the interior angles are the same.

Angle q is an interior angle of quadrilateral quad. An interior angle of a polygon is an angle inside the polygon at one of its vertices. The interior anglesof a polygon are the angles at each vertex on the inside of the polygon.

There is one per vertex. In order to find the measure of a single interior angle of a regular polygon a polygon with sides of equal length and angles of equal measure with n sides we calculate the sum interior angles or n 2 180 and then divide that sum by the number of sides or n. For each vertex of a polygon.

At the point where any two adjacent sides of a polygon meet vertex the angle of separation is called the interior angle of the polygon. We know that the polygon can be classified into two different types namely. Or we can say that the angle measures at the interior part of a polygon are called the interior angle of a polygon.

We have proven that the sum of the measures of the interior angles of a triangle is 180º. So for a polygon with n sides there are n vertices and n interior angles. An exterior angle of a polygon is made by extending only one of its sides in the outward direction.
