Inscribed angle its intersection points equals half of the central angle subtended by the chord. See also Tangent lines to circles. The inscribed angle theorem is used in many proofs of elementary Euclidean geometry of the plane. A special case of the theorem is Thales' theorem, which states that the angle subtended by a diameter is always 90°, i.e., a right angle. As a consequence of the theorem, opposite angles of cyclic quadrilaterals sum to 180°; conversely, any quadrilateral for which this is true can be inscribed in a circle. As another example, the inscribed angle theorem is the basis for several
How Many Licks? How Many Licks? "How Many Licks?" is a song by American rapper Lil' Kim featuring vocals by American musician Sisqó from her second studio album, "The Notorious K.I.M." (2000). It was released as the record's second single in 2000. Mario Winans and Sean Combs produced "How Many Licks?", and wrote it with Lil' Kim and Sisqó.
