Question

In the given figures below, decide whether l is parallel to m. please answer me fast​

Answer 1

Answer:

(i) parallel , (ii) not parallel , (iii) parallel , (iv) not parallel.

Step-by-step explanation:

in (i),

126°+44°=180°

so, sum of co interior angles is 180°.

So, it is parallel

in (ii),

vertically opposite angles are equal.

so, 75°=75°

now sum of co interior angles is 75°+75°=150°

So, it is not parallel.

in (iii),

vertically opposite angles are equal.

so, 57°=57°

now sum of co interior angles is 123°+57°=180°

So, it is parallel.

in (iv),

vertically opposite angles are equal.

so, 72°=72°

now sum of co interior angles is 98°+72°=170°

So, it is not parallel.

hope it will be helpfull to you!
