Question

In the given figure, y = 108° and x = 71°.

Are the lines m and n parallel? Justify?​

Answer 1

Step-by-step explanation:

We have, x = 71 and y = 108

Now, x + y = 71° + 108° = 179°

So, x + y = 180°

But x and y are the interior angles formed by a transversal l of two

lines m and n.

It is known that, if the sum of the interior angles formed by a transversal of two distinct lines i 180°, then the two lines are parallel

:: line m is not parallel to line n.
