Central Angle -- from Wolfram MathWorld

A central angle is an angle whose apex (vertex) is the center O of a circle and whose legs (sides) are radii intersecting the circle in two distinct points A and B. Central angles are subtended by an arc between those two points, and the arc length is the central angle of a circle of radius one (measured in radians). The central angle is also known as the arc's angular distance. The arc length span… WebFeb 15, 2024 · Now, the central angle subtends an arc and the chord (base of the isosceles triangle) that is also being subtended by (or opposite to) an angle defined by this theorem.

Central and Inscribed Angles: Definitions and Examples

WebWhen two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal. This can also be understood in another way. The alternate interior angles can prove whether the given lines are parallel or not.
