Question

Point C is the center of the circle.

A figure shows a circle with center point C. Two tangents are drawn from the same external point S. Two tangents touch the circle at P and Q. R is a point in a circle. The line connects PC, QC, PR, and QR.

Central angle C and circumscribed angle S intersect the same arc, so the angles are
A. complementary
B. supplementary
C. equal
D. not related

Central angle C and inscribed angle R intersect the same arc, so measure of angle R is
A. one-half the measure of angle C
B. not related to the measure of angle C
C. equal to the measure of angle C
D. the complement of angle C

Answer 1

Central angle C and circumscribed angle S intersect the same arc, so the angles are
B. supplementary

Central angle C and inscribed angle R intersect the same arc, so measure of angle R is
A. one-half the measure of angle C
