Answer 2

Answer:

Step-by-step explanation:

In first figure

We now line l and m will be parallel when they hole any of the property of parallel lines

So

We now that interior angle on same side in parallel lines sum 180°

So 126°+44°=170°

So in first figure line l and m are not parallel

In fig 2.

Let the angle beside 70° be x

75°+x = 180° (linear pair)

X = 180°-75° = 105°

So corresponding angle are same in parallel lines

But 105 is not equal to 75°

Hence line l is not parallel to m

In fig 3.

Let the angle beside 57° be x

So 57°+x =180° ( triangle sum property)

X = 180°-57°=120°

Now corresponding angle are same in parallel lines

So, 120°=120°

Hence line l and m are parallel
