Circles: Central Angles, Arcs, and Chords

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

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

If Circle M is congruent to Circle O, then:

• all of their central angles must be congruent
• both circles have centers named "P"
• both circles have congruent radii
• both circles have X-Box Ones

In circle O, the radius is 4, and the measure of minor arc AB is 120 degrees. Find the length of minor arc AB.
