A polygon is a 2D shape with at least 3 sides. Polygons can be regular or irregular. If all angles and sides of a polygon are equal, the polygon is categorised as a regular polygon. Typical GCSE questions involve students being able to find missing angles in a variety of polygons. In this lesson students will learn how to find missing angles in any polygon by applying what they know about the sum of angles in a triangle and a quadrilateral.
