Central Angle Has vertex at the center of the circle. P is the center of the circle. <TPQ is a vertex angle

Arcs: Measure of minor arc = measure of the central angle. Measure of major arc = 360 – minor arc Ex 1: <BKC = 35 Find the measure of: Minor Arc Major Arc

Inscribed Angle – has a vertex on the circle! Measure of an inscribed angle = ½ its arc. Find the measure of JKL .

Opposite angles of Quadrilateral inscribed in a circle are supplementary.
