1).  “What makes a triangle a right triangle? How many different right triangles can be formed?”  Is it possible to get them all?

2).  Use the GeoGebra applet to explore the relationship between side lengths of 45-45-90 triangles and 30-60-90 triangles.

Make sure to create three of each triangle and record their measurements in the chart below.  Download the Table:   Angles and Sides of a Triangle
