8. If two tangent segments are drawn to a circle from an external point, then those segments are congruent.

A. Sometimes B. Never C. Always D. Not enough information

9. If a secant and a tangent intersect at the point of tangency, then the measure of each angle formed is one-half the measure of its intercepted arc.

A. False B. True C. Sometimes True D. Sometimes False

10. If two secants intersect in the interior of a circle, then the measure of an angle formed is one-fourth the sum of the measures of the arcs intercepted by the angle and its vertical angle.

A. False B. True C. Sometimes True D. Sometimes False

11. When two secants intersect a circle, the segments of the secants (the chord and the whole secant) are equal when multiplied together.

A. False B. True C. Sometimes True D. Sometimes False

12. If a diameter of a circle is perpendicular to a chord, then the diameter bisects the chord and its arc.

A. Sometimes B. Never C. Always D. Not enough information
