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? Neptunes has additional vocals from American artists Kelis, Lil' Cease, and Snoop Dogg. "How Many Licks?" was praised by music critics after its release and in retrospective reviews; the Neptunes remix also received positive reviews.
