What Is Interior And Exterior Angle. An angle formed outside a polygon by one side and an extension of an adjacent side. Interior and exterior angles add up to 180degree.
Angles 2 and 7 are ALTERNATE and angles 1 and 8 are ALTERNATE.

This property of a triangles interior angles is simply a specific example of the general rule for any polygons interior angles.
One triangle has angle measures of 61 and 70 degrees the other triangle has angle measures of 39 and 70 degrees.
Look at the example underneath. In geometry an angle of a polygon is formed by two sides of the polygon that share an endpoint. Interior angles refer to all those angles that are inside a shape. On the other hand the exterior angle is an angle that is made by the side of the shape and a line drawn out from an adjacent side.
