View 5 Sided Shape Interior Angles PNG. Circles and shapes that include curves are not polygons a regular pentagon has 5 equal sides and 5 equal angles. In geometry, all two dimensional shapes are known as polygons, so it can also be referred to as a the interior angle of a regular pentagon is 108 degrees and the exterior angle of a regular pentagon is 72 degrees.
The exterior angle theorem states that an exterior angle of a triangle is equal to the sum of the two opposite interior angles.
The difference between a rhombus and a rectangle or square is that its interior angles are only the same as their diagonal opposites. The most familiar is the regular pentagon (a) , with equal sides and equal angles, each measuring 108 degrees. To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. Triangles are one of the most fundamental geometric shapes and have a variety of often studied properties including this property of a triangle's interior angles is simply a specific example of the general rule for any polygon's interior angles.
