reSolve: Mechanical linkages – geometry proofs

This series of six lessons explores geometry proofs using real-world contexts focused on the dynamics of linkages and moving joints. Students use physical models and computer simulations, the lessons move from a view of geometry as a study to static diagrams to encompass movement. Each lesson is outlined in detail including curriculum links, vocabulary, materials needed, sample answers, discussion points and student resources such as links for simulations online. This sequence is part of the reSolve: Mathematics by Inquiry special topic 'Mechanical linkages and deductive geometry'.
