Activity Overview

Properties of Parrallelograms

Before the Activity

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.

During the Activity

Students will: 1. Construct a parallelogram. 2. Measure sides and angles to visualize the relationships between the sides and angles of a parallelogram. 3. Try to alter the properties of their construction by moving the vertices

After the Activity

Review student answers:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
