Image result for What is the sum of the interior angles of a quadrilateral Another way to calculate the sum of the interior angles of a polygon is to see how many triangles the shape is composed of. Quadrilaterals are composed of two triangles. Seeing as we know the sum of the interior angles of a triangle is 180°, it follows that the sum of the interior angles of a quadrilateral is 360°

3. So, the sum of the interior angles of a heptagon is 900 degrees.

4. Pentagon 108°

5. ?
