Activity Overview

The symmetry of a trangle on the coordinate plane is discovered through the 2X2 matrix transformations.

Before the Activity

Students should have access to either the TI-83 or TI-84 family of calculators.

During the Activity

This Word Document is a step by step procedure to transform an acute triangle by multiplication of matrices.

After the Activity

Review student results:

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