of a circle, given point | center |
a segment whose endpoints are the center and any point of the circle | radius |
a segment whose endpoints are on a circle | chord |
a chord that contains the center of a circle | diameter |
a line that intersects a circle in two points | secant |
a line in the plane of a circle that intersects the circle in exactly one point | tangent |
on a circle is an angle whose vertex is the center of the circle | central circle |
ACB, endpoints are AB | minor arc |
point C doesnt lie on AB | major arc |
is an arc with endpoints that are the endpoints of a diameter | semicircle |
is the measure of its central angle | measure of a minor arc |
is the difference between 360 degrees and the measure of the related minor arc | measure of a major arc |
two circles with the same radius | congruent circles |
two arcs with the same measure are . they are arcs of the same circle or congruent circles | congruent arcs |
an angle whose vertex is 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 | inscribed arc |
when two chords intersect in the interior of a circle each chord is divided into two segments | segments of the chord |
a segment that contains a chord of a circle and has exactly one endpoint outside the circle | secant segment |
the part of a secant segment that is outside the circle | external segment |
