Answer:

I don't know the answer sorry for that

Answer 2

property :-

if two lines are cut by a transversal and corresponding angles are congruent then the lines are parallel .

Step-by-step explanation:

here

angle 1 = 60

then angle 2 = (180 - angle 1)

= 180 - 60

= 120

and

angle 6 = 120

then angle 5 = (180 - angle 6)

= 180 - 120

= 60

1. angle 1 = angle 3= 60

2. angle 2 = angle 4= 120

3.angle 6 = angle 8 =120

4.angle 5 = angle 7 = 60

above angles are vertically opposite angles .

now

1 and 5 are congruent

2 and 6 are congruent

3 and 7 are congruent

4 and 8 are congruent

as shown in figure .

so these two lines are parallel
