1. In the figure,
y = 108° and x = 71°
X
Are the lines m and n
у
parallel ?
Justify​

Answer 1

Answer:

yes the lines m and n are parallel

Step-by-step explanation:

as y+x=180 degree .......interior angles

therefore line m and n are parallel ......interior angle test

simply angles formed on two lines made those two lines parallel

Answer 2

Answer:

we know that the

if interior angles in the same side of a transersal is supplementary .... then the lines are parallel

here y+ x = 108° + 71°

= 179°

which is not equal to 180°

thus the angles x & y do not form supplementary angels

hence m and n are non parallel lines
