Webarc. an angle that has the center of a circle as its vertex. central angle. a line segment that connects two points on a circle. chord. a figure with all of its points the same distance from the center. circle. the length around the exterior of a circle; measured in degrees in terms of an arc. circumference of a circle. Apollonius of Perga showed that a circle may also be defined as the set of points in a plane having a constant ratio (other than 1) of distances to two fixed foci, A and B. (The set of points where the distances are equal is the perpendicular bisector of segment AB, a line.) That circle is sometimes said to be drawn about two points. titans gm saints offer

"WebWe know that a reflex angle and its corresponding angle add up to 360°. Therefore, the degrees of a reflex angle can be easily calculated. For example, if an acute angle measures 56°, then its corresponding reflex angle will be 360° - 56° = 304°. Similarly, if an obtuse angle measures 97°, then its corresponding reflex angle will be 360° - 97° = 263°. " - Circle and its degrees
