This is a 17-page guide for teachers. It contains the definitions, properties and tests for parallelograms and rectangles. Proofs of the properties and tests are given. Constructions for parallelograms and rectangles are given.
The modules are written for teachers. Together with other resources, they provide the mathematical background to enable the teacher to plan the development of topics in their classrooms. This module relates to Module 9: Measurement and Geometry: introduction to plane geometry - teacher guide, Module 13: Measurement and Geometry: construction - teacher guide, Module 21: Measurement and Geometry: rhombuses, kites and trapezia - teacher guide, Module 14: Measurement and Geometry: congruence - teacher guide, and to several of the measurement modules. Together with several other modules these modules provide material for teaching the geometry components of the Australian Curriculum for years 7 to 10.
