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 Birds gets faster. The singer states that he's lonely without his girl and doesn't know what to do. The Kids covered the song the same year, lead vocalist Michael Griffith and Tony Borg singing to the Bee Gees backing tracks. The Kids never recorded again but the fact that they chose this song to record proves that the Saint Clair tapes were not discarded when the studio closed, and were presumably in Nat Kipner's hands. But Kipner today has no idea where they went to. How Many Birds "How Many Birds" is a song written by Barry Gibb, recorded by the
