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

• equal to twice the measure of its corresponding inscribed angle

• equal to the measure of its corresponding inscribed angle

• equal to half of the measure of its corresponding inscribed angle

• equal to four cups of wheat flour

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
