Question

to verify that the angle in the same segment of a circle is equal
​

Answer 1

Step-by-step explanation:

Since the chord AB = chord CD and ∠APB superimposes ∠DRC, their arcs are same. When two angles superimpose each other it means their two arms lie on one another. This verifies that angles in the same segments are equal. We verified that two angles subtended by the chord of a circle in the same segment are equal.
