Answer:
Theorem 78: In a circle, if two chords are equal in measure, then their corresponding minor arcs are equal in measure.
The converse of this theorem is also true.
Theorem 79: In a circle, if two minor arcs are equal in measure, then their corresponding chords are equal in measure.
Example 1: Use Figure 2 to determine the following. (a) If AB = CD, and = 60°, find m CD. (b) If m = and EF = 8, find GH.
