Please help me answer this question

Answer 1

Explanation:

BC is the bisector of
`\angle ABQ`

`\therefore \angle ABC \cong \angle CBQ..(1)\\</p><p>\angle CBQ \cong \angle CAB..(2) \\(\angle 's\: in \: alternate\: segments) \\`

From equations (1) & (2)

`\angle ABC \cong \angle CAB\\</p><p>\therefore AC = BC`

(Because sides opposite to equal angles are equal)

Hence Proved
