Question

If a || b and c is the transversal, then the sum of $\angle 5$ and $\angle 2$ is .

• A. 180°
• B. 90°
• C. 45°

Answer 1

The correct option is A 180°


Given a || b and c is the transversal, then $\angle 5$ and $\angle 2$ form co-interior angles which are supplementary.

So, $\angle 5+\angle 2$ = 180°.
