1
Q
If two chords intersect in the interior of a circle, then
A
The measure of each angle is half the sum of the measures of the arcs intercepted by the angle and it’s vertical angles
2
Q
If a tangent and secant, to tangents, or to secant intersect in the exterior of a circle, then
A
The measure of the angle formed is half the distance of the measure of the intercepted arcs
3
Q
It’s AC and BD are cords THEN
A
AE • EC = DE • EB
4
Q
If CA and CE are secants then
A
CA • CB = CE • CD
5
Q
If CA is a secant and CD is a tangent, then
A
CA • CB = CD squared
6
Q
If A tangent and accord intersect at a point on a circle, then
A
The measure of each angle formed is half the measure of its intercepted arc
