Question

If a transversal intersects two parallel lines, then the consecutive interior
the same side of the transversal are
(1) complementary
(2) supplementary
3 equal
(4) None of these​

Answer 1

Answer:

2) supplementary

If AB and CD are two parallel lines

EF is the tranversal line which bisects AB and CD at points G and H

Now,<EGB =<AGH( opposite angles)

<BGH=<CHG(opposite angles)

so,<CHG+<AGH=180°
