In the diagram below, we are given a circle where angle abc is an inscribed. This circle is called the circumcircle or circumscribed circle, and the vertices are said to be concyclic. If abcd is inscribed in ⨀e, then m∠a+m∠c=180° and m∠b+m∠d=180°. If a quadrilateral inscribed in a circle, then its opposite angles are supplementary. It turns out that the interior angles of such a figure have a special in the figure above, if you drag a point past its neighbor the quadrilateral will become 'crossed' where one side crossed over another. Opposite angles in any quadrilateral inscribed in a circle are supplements of each other.
An angle inscribed across a circle's diameter is always a right angle the angle in the semicircle theorem tells us that angle acb = 90°.
