Properties of tangent lines
1.
PA is a tangent to circle O. If the measure of angle APO is 25°,
find the measure of angle AOP.
2.
From point P, a secant containing the center of circle O and a tangent to the
circle are drawn. If the measure of angle APB is 35°, find
the measure of angle ABP.
3.
PA is a tangent to circle O of radius 12 at A. If the distance between
point P and the center of the circle is 20, find the length of the tangent
segment PA.
