Question:
The measure of an angle formed by two secants intersecting outside a circle equals to:
a) {eq}\frac{1}{2} {/eq} The sum of the intercepted arcs.
b) {eq}\frac{1}{2} {/eq} The difference of the intercepted arcs.
c) {eq}\frac{1}{2} {/eq} The measure of the intercepted arc.
Secant:
The term secant comes from the Latin secare which means to cut. A secant line intersects the circle at exactly two points and divides the circle into intercepted arcs. The larger arc is called the major arc and the smaller arc is the minor arc. If the secant passes through the center, then the two arcs are of equal measure.
