 what makes up the sides of an inscribed angle? two chords the measure of a central angle equals the measure of the intercepted arc the measure of an exterior angle formed by two secants equals one-half the difference of the two intercepted arcs the measure of the angle formed by two intersecting chords equals one-half the sum of the arc intercepted by the angle and the arc intercepted by the angle vertical to the angle. the measure of an angle formed by the intersection of a tangent and a chord equals one-half the measure of the intercepted arc. parallel chord cut off congruent arcs the sum of the arc measures of a circle is 360 degrees the sum of the arc measures of a circle is 360 degrees a radius drawn to a tangent line at the point of tangency is perpendicular to the tangent line congruent chords have congruent arcs congruent central angles have congruent chords congruent arcs have congruent chords the measure of the exterior angle formed by a tangent line and a secant line is equal to one-half the difference of the two intercepted arcs. the measure of an inscribed angle equals one-half the measure of the intercepted arc the measure of the arc of a semicircle is 180 degrees
