The set of all points in a plane that are equidistant from a given point | circle |
A give point that is equidistant to all the points in a plane | center of circle |
The distance from the center of a circle to a point on the circle. A segment whose endpoints are the center of the circle and a point on the circle. | radius of circle |
Two circles that have the same radius. | congruent circles |
A chord that passes through the center of the circle. The distance across a circle, through its center. | diameter of circle |
A segment whose endpoints are points on the circle. | chord of a circle |
Circle that intersect in one point. | tangent circles |
Circles that have a common center. | concentric circles |
A line or segment that is tangent to two circles. A common internal tangent intersects the segment that joins the centers of the two circles. A common external tangent does not intersect the segment that joins the centers of the two circles. | common tangent |
All points of the plane that are inside a circle. | interior of a circle |
All points of the plane that are outside a circle. | exterior of a circle |
A line that intersects a circle in exactly one point. | point of tangency |
An angle whose vertex is the center of a circle. | central angle of a circle |
Part of a circle measures less than 180 degrees. | minor arc |
Part of a circle that measures between 180 degrees and 360 degrees. | major arc and its measure |
An arc whose endpoints are the endpoints of a diameter of the circle. | semicircle |
Two arcs of the same circle or of congruent circles that have the same measure. | congruent arcs |
An angles whose vertex in on a circle and whose sides contain chords of the circle. | inscribed angle |
The arc that lies in the interior of an inscribed angle and has endpoints on the angle. | intercepted arc |
A polygon whose vertices all lie on a circle. | inscribed polygon |
A circle with an inscribed polygon. | circumscribed circle |
A segment that is tangent to a circle at an endpoint. | tangent segment |
A segment that intersects a circle in two points, with one point as an endpoint of the segment. | secant segment |
The part of a segment that is not inside the circle. | external segment |
The set of all points that satisfy a given condition or a set of given conditions. | locus |
A segment that intersects a circle in two points, with one point as an endpoint of the segment. | secant tangent |
