Question

If angle 2 =120 and angle 5 =60 show that m is parallel to n

Answer 1

Answer:

Step-by-step explanation:

Given: Angle 2 = 120, Angle 5 = 60, P is the transversal.

Image: Provided below

Solution: 

Here, Angle 2 is given to be 120. 

As Angle 2 and Angle 1 form a linear pair, the sum of the angles must be 180.

Angle 2 + Angle 1 = 180

120 + Angle 1 = 180

Angle 1 = 180 - 120

            =  60

But, Angle 5 is given to be 60.

Thus, Angle 1 = Angle 5 = 60As the corresponding angles are equal, m is parallel to n.
