 circle The set of points in a plane that area given distance from a given point in the plane. The given point is the center, and the given distance is the radius. center of a circle the point inside the circle radius of circle the distance from the center to the side of the circle congruent circles Circles that have congruent radii. diameter of circle a chord that passes through the center of the circle. the distance across the circle chord, secant a segment whose endpoints are points on the circle tangent circles Coplanar circles that are tangent to the same line at the same point. concentric circles Circles that lie in the same plane and have the same center. common tangent a line of segment that is tangent to two circles interior of a circle all points of the plane that are inside the circle exterior of a circle all points of the plane that are outside the circle point of tangency A line in the plane of the circle that intersects the circle in exactly one point, called the point of tangency. central angle An angle with its vertex at the center of the circle. minor arc and its measure PART of a circle that measures between 180 and 360 major arc and its measure part of a circle that measures less than 180 semicircle The two arcs of a circle that are cut off by a diameter. The measure of a semicircle is 180. congruent arcs Arcs, in the same circle or in congruent circles, that have equal measures. inscribed angle An angle whose vertex is on a circle and whose sides contain chords of the circle. intercepted arc the arc that lies in the interior of an inscribed angle and has endpoints on the angle inscribed polygon a polygon whose vertices all lie on a circle circumscribed circle a circle with an inscribed polygon tangent segment a segment that is tangent to a circle at an endpoint secant segment a segment that intersects a circle in two points, with one point as an endpoint of the segment external segment the part of a secant segment that is not inside the circle locus the set of all points that satisfy a given condition or a set of given conditions
