Question

in figure 2.18,y=108° and x=71° are the lines m and n parallel? justify?

Answer 1

Hi ,

We know that ,

Sum of pair of interior angles same

side of the transversal are

supplementary then the lines are

parallel.

According to the problem given,

x and y are pair of interior angles

same side of the transversal.

x+ y = 71 + 108 = 180°

Therefore,

m and n are parallel lines .

I hope this helps you.
