An angle is a(n) ______ if the vertex is on a circle and the sides of the angle are shords of the circle.

• right angle

• acute angle

• inscribed angle

• intercepted angle

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 bisects a chord (that is not a diameter), then:

• it is a secant

• it is parallel to the chord

• it is perpendicular to the chord

• it is just shaking out the sillies
