Description:
A chord of a circle is a straight line segment that connects two points on the circumference of the circle. It lies entirely inside the circle and can vary in length and position within the circle. If a chord passes through the center of the circle, it becomes the diameter, which is the longest possible chord for that circle. The perpendicular from the center of the circle to a chord bisects the chord, dividing it into two equal segments. Chords play a fundamental role in circle geometry and are used to establish various relationships within circles.
Recall that two circles are congruent if they have the same radii. Prove that equal chords of congruent circles subtend equal angles at their centres.
