reSolve: mechanical linkages – quadrilaterals

This unit is part of the reSolve ‘Mechanical Linkages and Deductive Geometry’. This unit focuses on investigating geometry, starting with real-life objects, then making working models and finally using pre-prepared dynamic geometry software. This unit uses the properties of quadrilaterals, especially rhombuses and parallelograms, to explain how these tools and objects move. The lessons are independent of each other and can be taught in any combination.
