We’re at the Polygons annual party ... they’re all the four-sided shapes with internal angles that total 360 degrees. So who have we got here then? Oh of course, the Square, hi.

A regular polygon is a polygon with all equal sides and angles ... The reason interior angles in a quadrilateral sum to 360° is because a quadrilateral can be divided into two triangles.

div \text{number of sides}\) If the side of a polygon is extended, the angle formed outside the polygon is the exterior angle. The sum of the exterior angles of a polygon is 360°. The sum of exte ...
