**A polygon is a 2-dimensional closed shape with straight sides.**

**The angles in a quadrilateral add up to 360º.**

**The simplest polygon is a triangle (a 3-sided shape). Polygons of all types can be regular or irregular.**

**A regular polygon has sides of equal length, and all its interior angles are of equal size.**

**Irregular polygons can have sides of any length and angles of any size.**

**Interior angle of a regular polygon = sum of interior angles ÷ number of sides**

**The exterior angles of a regular polygon **always add up to 360°, so the exterior angle of a regular hexagon is
