A line that lies in the plane of a circle and that intersects the circle at exactly one point. (The Point of Tangency)
A segment from a point on the circle or a sphere to the center.
Circles that lie in the same plane that share the same center.
Two points on a circle and the continuous part of the circle between the points.
Angle whose vertex is the center of the circle and whose side contain radii of the circle Central Angles are equal to the intercepted arc.
Angles whose vertex lies on the circle and whose sides contain chords of the circle. Inscribed Angles are equal to HALF the intercepted arc.
Distance around a circle, that is, the perimeter of the circle.
A fraction of the circumference of a circle defined by the arc.
An arc of a circle whose endpoints are the diameter. Its measure is 180.
An arc of a circle whose length is less than the length of a semicircle. Its measure is greater than 0 and less than 180. The arc can be named by its endpoints or with a third point inside.
An arc of a circle whose length is greater than the length of a semicircle. Its measure is greater than 180 and less than 360. The arc is named by its endpoints and a third point inside.
