How to find the sum of interior angles for a heptagon

The video tutorial covers the basics of polygons, including the number of sides for various types such as triangles, quadrilaterals, pentagons, hexagons, and more. It explains how to calculate the sum of interior angles using the formula (n-2) * 180, where n is the number of sides. The tutorial demonstrates this calculation with a heptagon, showing that its interior angles sum to 900 degrees.
