Circles

In a circle (or congruent circles), the measure of an arc is:

• equal to half of the measure of its corresponding central angle
• equal to the measure of its corresponding central angle
• equal to the measure of its circle's radii
• only calculated by taking the square root of dragon taxis

In a circle (or congruent circles), congruent central angles:

• are 60 degrees
• have congruent points
• have congruent arcs
• spell out the word "dracula"

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
