Understanding key terms: radius, diameter, chord, arc, sector, and segment. Properties of Tangents and Secants: Tangents and their properties with respect to circles. Secants and their properties. Angle Subtended by an Arc: Understanding the angle subtended by an arc at the center and at the circumference. Cyclic Quadrilaterals: Properties of cyclic quadrilaterals. Understanding the relationships between opposite angles of a cyclic quadrilateral. Construction of Tangents and Normals: Constructing tangents and normals to circles from external points.
