1. Copying Segments Create the length 2AB AB

2. Congruent Radii

3. What do we call the compass length? Say we open our compass to this length -------------------> Then, draw a circle using point A as your center: Segment AB is now called the __________ of circle A. radius

4. Copying Segment AB Step 1: Draw a RAY. Step 2: Open your compass to AB. Step 3: Mark off AB on your ray. A’ B’ What do we know about segments AB and A’B’? They are congruent radii.

5. Bisecting Segment AB What is the next step? Name some radii (plural for radius). CDCD radius
