WebJan 31, 2024 · The entire circle has a degree measurement of 360°. Meanwhile, its half (i.e., semicircle) measures 180°. There’s another way to measure arcs and central angles of a circle aside from using degrees. This is by using “radians.” A radian is the measure of the arc formed by a central angle whose length is equal to the circle’s radius. 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°.

WebSep 15, 2024 · Theorem 2.5. For any triangle ABC, the radius R of its circumscribed circle is given by: 2R = a sinA = b sin B = c sin C. Note: For a circle of diameter 1, this means a = sin A, b = sinB, and c = sinC .) To prove this, let O be the center of the circumscribed circle for a triangle ABC. 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. george thorogood the hard stuff
