Proving rectangles
WebbIn a previous lesson students used strips and fasteners to make conjectures and practice proofs about quadrilaterals. In this lesson students prove the important result that all rectangles are parallelograms. Then groups of students tackle different relationships among quadrilaterals and their diagonals.
