Question

in the adjoining figure lines m and n are parallel and l is the transversal intersecting them. if angle A=100, then find all orther angles. and if m is not parallel to n, then can we find all the other angles ?

Answer 1

The angle intersect the parallel line is same for both that is 100°

Other side of anlge = 180° - A = 180° - 100° = 80°

All angles are same as 100° & 80° on those intersection lines which is parallel.

Please refer the diagram

Answer 2

a= 180-100=80 hope this helps you
