Question

If a || b || c, and m is the transversal, then 1, 2 and 3 form angles.

• A. corresponding
• B. co-interior
• C. alternate exterior

Answer 1

The correct option is A corresponding

All the mentioned angles lie on the same side of the transversal and they have different vertices.

When a || b,1 will be the exterior angle while 2 will be the interior angle. Hence, 1 and 2 are corresponding angles.
When b || c, 2 will be the exterior angle while 3 will be the interior angle. Hence, 2 and 3 are corresponding angles.
