Chord
A segment whose endpoints lie on a circle
Central Angle
An angle less than 180 degrees whose vertex lies at the center of a circle
Inscribed Angle
An inscribed angle is an angle whose vertex lies on a circle and whose sides contain chords of the circle.
Arc
A continuous portion of a circle consisting of two points
Minor Arc
A minor arc is an arc whose points are on or in the interior of a corresponding central angle
Major Arc
A major arc is an arc whose points are on or in the interior of a corresponding angle
Semicircle
A semicircle is an arc whose endpoints are on the endpoints
Arc Addition Postulate
The measure of an arc formed by two adjacent arcs is the sum of the measures of the two arcs.
Intercepted Arc
Consists of endpoints that lie on the sides of an inscribed angle and all the points of the circle between them
Inscribed Angle Theorem
The measure of an inscribed angle is equal to half the measure of its intercepted arc
Adjacent Arcs
Arcs of the same circle that intersect in exactly one point.
