Question

In the given figure decide whether l || m?

Justify your answers with valid reasons.

Answer 1

Step-by-step explanation:

We have,

Let us assume that l || m

then,

(126 + 44)° = 180° (co interior angles)

But the sum is 170°

clearly they are not co interior angles.

Hence our assumption is wrong.

Thus, l is not parallel to m.
