9-6 Other Angles
Theorem 9-9The measure of an angles formed by two chords that intersect inside a circle is equal to half the sum of the measures of the intercepted arcs.
Theorem 9-10The measure of an angle formed by two secants, two tangents, or a secant and a tangent drawn from a point outside a circle is equal to half the difference of the measures of the intercepted arcs.
