Angle subtended by chord
In Class 9 Mathematics, this topic from the chapter Circles explains how a chord forms an angle at a point on the circle and at the centre. Students learn to identify the angle subtended by a chord, understand the relationship between the central angle and the angle subtended by the same chord at the circumference, and apply the result that angles in the same segment are equal. They also use diagrams and simple reasoning to solve circle-based problems, including cases involving a semicircle and a right angle.
