Investigating Properties of Parallelograms
Given different parallelograms, geometers make conjectures about their properties. They then work in small groups to prove (or disprove) their conjectures. The activity provides many opportunities for making conjectures and critiquing...

Investigating Properties of the Diagonals of Quadrilaterals
Tenth graders investigate quadrilaterals. In this geometry lesson, 10th graders investigate the properties of the diagonals of quadrilaterals. The dynamic nature of Cabri provides opportunity for conjecture and verification. The...
Inscribed Quadrilaterals and Parallelograms
Young scholars differentiate between inscribed quadrilaterals and parallelograms. In this geometry activity, students identify the shaped of the polygons when it is inscribed inside of a circle. They calculate the missing angles of the...
