# Transversals & Corresponding Angles

## 1. Create line AB; 2. Create line CD that crosses line AB; 3. Label the intersection point E; 4. Translate points A, B, and line AB by directed segment ED.

What is the measure of angle AEC? What is the measure of angle A'DE? How are they related?

## Rotate point B and line AB 180° around point D. Label the new point of intersection F.

What is the measure of angle AEC? What is the measure of angle B'FD? How are they related?
