Proof: Vertical Angles Theorem

Type your responses the prompts 1-4. Then complete the exercise below the applet. 1. What theorem is being demonstrated in the applet? 2. State the theorem. 3. What type of transformation is being demonstrated in the applet? And what information do you need to include to precisely describe the transformation?

A. Draw a diagram representing the transformation above. Label any objects you will need to refer to in a precise description of the rotation. B. Write a proof of the vertical angles theorem. Refer to your diagram in the proof, and give precise definitions of any geometry vocabulary terms you use.
