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

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

• it bisects the chord
• it bisects the corresponding arc
• it bisects BOTH the chord and its arc
• none of these answers are correct

A chord that passes through the center of the circle is a ________.

• chord
• diameter
• radius
• tangent

In a circle, the perpendicular bisector of a chord:

• is tangent to the circle
• is the diameter
• is a right triangle
• eats frosted flakes for dinner
