Question

In the figure, angle 1= 60° and
angle 6 = 120° show that the lines
m and n are parallel urgent!!!​

Answer 1

<6=120°

So, <5=180-120=60°

Now angle 1 angle 5 are corresponding angles

and angle 1 is equal to angle 5 hence corresponding angles are equal so the lines are parallel

Answer 2

Step-by-step explanation:

Since, angle 2 = angle 6 (corresponding angles)

Therefore angle 2 = angle 6 = 120 degree

Similarly, angle 1 = angle 5 = 60 degree

In m, angle 1 + angle 2 = 180 degree (linear pair)

In m, angle 1 + angle 2 = 180 degree (linear pair) = 60 degree + 120 degree = 180 degree

In m, angle 1 + angle 2 = 180 degree (linear pair) = 60 degree + 120 degree = 180 degree

In n, angle 5 + angle 6 = 180 degrees

= 60 degree + 120 degree = 180 degrees
