1. In a circle, if two chords are congruent, then their corresponding minor arcs are:
Congruent
Supplementary
Complementary
Proportional
2. A diameter of a circle is perpendicular to a chord. What does this imply about the chord and its arc?
It bisects the chord but not the arc.
It bisects the arc but not the chord.
It bisects both the chord and its arc.
It has no relation to bisecting either.
3. In a circle, if two chords are equidistant from the center, then the chords are .
4. The measure of a central angle is to the measure of its intercepted arc.
5. Consider a circle with center O and a chord AB. If the radius of the circle is 10 cm and the length of the chord AB is 16 cm, find the distance from the center O to the chord AB. Show your work.
