How to find interior and exterior angles. Draw a straight line from point a to each other vertex in the polygon. The exterior angles of a polygon add up to 360. The sum of the exterior angles of a triangle and any polygon is 360 degrees.

The sum of the remote interior angles is equal to the non adjacent exterior angle. How to calculate the sum of interior angles drawing triangles draw the polygon whose angles you need to sum. How to find angles interior exterior and arc angles wyzant.

When we add up the interior angle and exterior angle we get a straight line 180 they are supplementary angles. Interior and exterior angles of triangles suppose the building that you live in is polygonal in shape. You may need to find exterior angles as well as interior angles when working with polygons.

Exterior angle the exterior angle is the angle between any side of a shape and a line extended from the next side. When we add up the interior angle and exterior angle we get a straight line 180. The exterior angle is the angle between any side of a shape and a line extended from the next side.

A polygon is any flat shape with straight sides. 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 anglesor red n 2 cdot 180 and then divide that sum by the number of sides or red n. If you start walking around the building on any side as you turn each corner the angle you pivot is the exterior angle of that corner.

The remote angles are the two angles in a triangle that are not adjacent angles to a specific exterior angle.
