# Lesson 2 Practice/Cool Down

This diagram was created by starting with points A and B and using only straightedge and compass to construct the rest. All steps of the construction are visible. Describe precisely the straightedge and compass moves required to construct the line EF in this diagram.

## Write your response here:

Here is segment AB and a point C. Create a circle centered at C whose radius is the length of AB. Mark a point on the circle and label it D. Draw line CD and label its other intersection with the circle as point E.
