Introduction to plane geometry (Years 7 and 8)

This module from the AMSI 'The Improving Mathematics Education in Schools (TIMES) project' is for teachers who wish to consolidate their content knowledge on the topic of two-dimensional geometry. It looks at parallel lines, points, angles and the angle sum of a triangle. There are sections that provide history and context for the topic, as well as exercises and examples of how to present and explain the concepts to students.
