Question

in the given figure if angle2=120° and angle5=60° ,then show a||b.​

Answer 1

Answer: Proved Below.

Step-by-step explanation:

Given ∠2= 120°

∠5=60°

Now, ∠2+ ∠5= 120°+ 60° = 180°

Thus it proves that the co-interior angles are supplementary.

∴a || b.

Answer 2

In the figure, ∠1 = 60° and ∠6 = 120°. Show that the lines m and n are parallel.
