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