Angles of Triangles

What are Interior and Exterior Angles Interior Angles are angles inside a polygon. When the sides of a polygon are extended, other angles are formed. Exterior Angles are the angles outside of the polygon that are adjacent to the interior angles.

Interior Angles Measures of a Triangle
