Explore relationships (including congruence and similarity) among classes of two- and three-dimensional geometric objects, make and test conjectures about them, and solve problems involving them.
This activity will help students visualize the construction of a parallelogram and the properties of side, angles and diagonals.
Extensions are built into the construction.
