G5.10: Angle properties of polygons

Purpose

This interactive learning module supports students to explore rules for the interior and exterior angles of polygons.

Achievement Objectives
GM5-5: Deduce the angle properties of intersecting and parallel lines and the angle properties of polygons and apply these properties.
Specific Learning Outcomes
  • Recognising interior and exterior angles of polygons.
  • Using the properties of angles around a point and angles on a line.
  • Finding the sum of exterior and interior angles of a polygon.
  • Using the sum of interior angles of a triangle to solve problems.
