Circle exterior angles
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. WebJan 24, 2024 · Q.7. What are the cyclic properties of a circle based on the measure of angles? Ans: The cyclic properties of a circle based on the measurement of its angles are 1. A cyclic quadrilateral (a quadrilateral inscribed in a circle) has supplementary angles. 2. The exterior angle of a cyclic quadrilateral is equal to the opposite interior angle.
