Question

are the follwing in paralles justify your answer​

Answer 1

1. not parallel because the angle should have been 100° to satisfy parallel lines.

2. It is parallel as it obeys alternate interior angles.

3.It is not parallel as it doesn't follow co interior angles

4. it is parallel as it obeys alternate exterior angles.

5. It is not parallel.

Hope it helps you...

Answer 2

Refer To image first ,

Question (1)

angle 2 = angle 6 = corresponding angles = 80°

now, angle 7 = 180-80 = 100°

so, its not parallel ...

______________________________

Question (2)

angle 1 = angle 5 = corresponding angles = 100°

so,

angle 8 = 180-80 = 80° ☑️

That means it is parallel ...

______________________________

Question (3)

obviously not parallel , as sum of interior angles between parallel lines is equal to 180° .....

Here it is = 130+45 = 175°

______________________________

Questio (4)

Angle 4 = angle 7 = exterior angles = 75°

so, angle 6 = 180° - 75° = 105°

But angle 6 is given 75°

so, not paralllel.....

______________________________

Question (5)

angle 1 = angle 5 = corresponding angles = 80°

so,

angle 8 = 180-80 = 100°

But it is given 120° ..

so, not parallel ....
