#### Proportional Relationships of Triangles - An Activity

This is a two-part activity and will most likely take two 50 - 55 minute class periods – one day per part. Part I (Day one) is a hands-on activity that allows students to work together on computers to discover the proportional relationship between a pair of similar right triangles. Ideally, you will have a class set of computers or a computer lab you could use for this lesson. If you don't have access to these resources you can run a demonstration on one computer and project it for the class and have students come up to manipulate the triangles.
