Question

prove that angle in the same segment is equal class 9​

Answer 1

Answer:

Angles in the same segment are equal'

The 2 angles D and E are both sitting on the same piece of the circle, BC. ... It is also clear that A, the 'angle at the centre' BAC, is 'looking at' the same arc BC as the angles D and E. So Theorem 1 applies: 'the angle at the centre is twice the angle at the circumference';

I am also in class 9
