In a circle (or congruent circles), congruent arcs:

• have congruent chords
• have congruent points
• are twice the measure of their radii
• can climb a hippo

Use chords to solve for x

• x = 35^o
• x = 50^o
• x = 70^o
• x = 140^o

In a circle (or congruent circles), chords that are the same distance from the center:
