|---|---|
| circle | The set of all points in an plane that are equidistant from a given point, called the center of the circle |
| center | Given point in the middle of circle |
| radius | The distance from the center of a circle to a point on the circle |
| diameter | A chord that passes thru the center of a circle. The distance across the circle. |
| chord | A segment whose end points are points on the circle |
| secant | A segment that intersects a circle in two points, with one point as an endpoint of the segment. |
| tangent | A line in the plane of a circle that intersects the circle in exactly one point |
| concentric | Coplanar circles that have a common center |
| central angle | An angle whose vertex is center or the circle |
| inscribed angle | An angle whose vertex is on a circle and whose sides contain chords of the circle |
| minor arc | An arc that is less that 180 |
| major arc | An arc that is more than 180 |
| semicircle | When the endpoints of an arc are the endpoints of a diameter |
| intercepted arc | The arc that lies in the interior of an inscribed angle and has endpoints on the angle |
| inscribed | If all the vertices of a polygon lie on a circle |
| circumscribed | A circle with an inscribed polygon |
| equidistant | Equal distance |
| apothem | The height of a triangle between the center and two consecutive vertices of the polygon |
| circumference | The distance around a circle |
| arc length | Portion of the circumference of a circle |
| area | Equals Pie R squared |
