Front

What is the definition of an inscribed angle?

Back

An inscribed angle is an angle formed by two chords in a circle which have a common endpoint.

Front

What is the formula for finding the measure of an angle formed by two intersecting chords inside a circle?

Back

The measure of the angle is equal to half the sum of the measures of the intercepted arcs.
