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

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

• are similar
• have the same name
• are congruent to each other
• are walking dead

In a circle, if a diameter is is perpendicular to a chord, then:

• it bisects the chord
