Session 5: Dissections and Proof
 

In this session, you will begin to use the properties of figures to solve geometric problems and to justify their solutions. You will also use visualization and geometric reasoning to solve cutting tasks.

In This Session:

Part A:

Tangrams

Part B:

Cutting Up

Part C:

The Midline Theorem

Homework

 


For information on required and/or optional materials for this session, see Note 1.
