1. The two triangles are similar. Play with the sliders to see different sizes and shapes of 2 similar triangles. What is the same no matter what changes? (I.e. What makes the triangles "similar?")[br]2. Compute [math]\frac{AB}{PQ}[/math] , [math]\frac{BC}{QR}[/math] and [math]\frac{CA}{RP}[/math] for at least 2 similar triangle pairs. [br]3. What do you notice about the ratios?
