Question

Given O below, the arcs wx and 72 must be congruent.

Answer 1

B

Explanation:

For the arcs WX and YZ to be congruent.

The angles subtended at the centre of the circle must be congruent.

This is not the case here as arc WX subtends 80° and arc YZ subtends 35°

Thus arc WX and arc YZ are not congruent.
