Angles in Dilation

The following exercises will introduce a new set of triangle similarity theorems that we have been working towards for the past two weeks. Answer the questions as well as you can, and pay attention to all new triangle similarity theorems you encounter. We will be adding these to our special notebooks today. ___________________________ Interact with the applet below for a few minutes, then answer the following question. What is the effect of a dilation on the angles of a triangle?
