Question

In the figure angle 2 = 120 degrees and angle 5 = 60 degrees, show that m||n

Answer 1

Answer:

IF angle 2 is 120 degree than angle 1 is 60 degree and it is given that angle 5 is 60 degree.

So corresponding angle are equal than m//n

Answer 2

Step-by-step explanation:

angle 3= 180- angle 2 ( straight angle)

angle 3= 180- 120

angle 3= 60°

since, angle 3= angle 5

therefore, m||n ( alternate angles)
