Intersecting Chords Form A Pair Of Congruent Vertical Angles - Diagram 1 in diagram 1, the x is half the sum of the measure of the intercepted arcs ($$ \overparen{abc} $$ and $$ \overparen{dfg} $$) 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.
