Different Types of Polygons A polygon is a plane figure that is made by joining the line segments, where each line segment meets exactly two other line segments. The intersection point of two line segments is called the vertex of the polygon. Polygons are of two types: (i) Regular polygon (ii) Irregular polygon Regular and […]

Exterior Angles of Polygons Progressing on from finding angles in parallel lines students in Year 8 learn how to calculate the exterior angles of polygons. As learning progressing more able students are challenged to find the number of sides a regular polygon has when given its exterior angle.

Students learn how to calculate interior angles of polygons. Learning progresses from finding an interior angle using 180 - exterior angle to calculating the sum of all the interior angles for any regular polygon. More able students are challenged to find the number of sides a polygon has when given its interior angle.
