Circle exterior angles
WebThe exterior angle of a cyclic quadrilateral is equal to the interior opposite angle. A radius or diameter that is perpendicular to a chord divides the chord into two equal parts and vice versa. A tangent to a circle is perpendicular to the radius drawn to the point of tangency. When two segments are drawn tangent to a circle from the same ...

WebThe supplement of an interior angle is called an exterior angle, that is, an interior angle and an exterior angle form a linear pair of angles. There are two exterior angles at each vertex of the polygon, each determined by extending one of the two sides of the polygon that meet at the vertex; these two angles are vertical and hence are equal.
