Angles formed by intersecting Chords
Theorem: The measure of the angle formed by 2 chords that intersect inside the circle is $$ \frac{1}{2}$$ the sum of the chords' intercepted arcs.

Note: This theorem applies to the angles and arcs of chords that intersect anywhere within the circle. It is not necessary for these chords to intersect at the center of the circle for this theorem to apply.
