- inscribed angle–an angle whose vertex lies on a circle and whose sides are chords of a circle
intercepted arc–the arc marked off by an inscribed angle
- inscribed angle theorem–the measure of an angle inscribed in a circle is equal to half the measure of the intercepted arc.
right-angle corollary–if an inscribed angle intercepts a semicircle, then the angle is a right angle.
arc-intercept corollary–if two inscribed angles intercept the same arc, then they have the same measure.
