Question

In fig angle 1 =60° and angle 6 =120° .Show that the lines m and n are parallel​

Answer 1

Step-by-step explanation:

If angle 1 is 60°, then angle 4 is equal to 120° because they are a linear pair.

angle 6 and angle 4 are alternate interior angles.

And, angle 6= angle 4.

Hence, they are parallel lines since the alternate interior angles are equal.
