#1 Congruent Segment

a. Create a "reference line" CD below segment AB. b. Create a circle with radius AB. c. Place the center of this circle at C. d. Label the intersection of the circle and the line as E. e. Create segment CE. f. Change the color/thickness of your new segment. g. Verify that the segments are congruent using the distance tool.

Analysis

How did we know that the circle used would create a segment CE that is congruent to segment AB before using the measurement tool?
