AB is chord of a circle with centre O and C and D lie on the same side of AB.

If  $\large \angle ACB=60^0, \; then \; \angle ADB\;= 60^0$ Angles in the same segment are equal

If $\angle ACB=60^0, \; then \; \angle AOB\;=120^0$  Angle at the centre is double the angle at the circumference.

$\angle ADB\;and\; \angle AOB\; is\; 60^0, 120^0$

are respectively equal to
