Question

l || m || n and p is a transversal line find angle 1,2,3

​

Answer 1

Answer:

for the first one

angle 4 +60=180 supplementary angles

angle 4 = 180-60 = 120

angle 4 = angle 1  corresponding angles

= 120

angle 1 = angle 2 corresponding angles

= 120

angle 3= angle 2  vertically opposite

= 120  

for the second one

we can mark a angle as angle 4 under 60

angle 4 +60=180 supplementary angles

angle 4 = 180-60 = 120

angle 3 = angle 4

= 120                      corresponding angles

angle 1 + angle 3 = 180

angle 1+120 = 180

hence angle 1 = 180-120 = 60

angle 3 = angle 2   alternate angles.

= 120    

Note add the degree symbol by yourself
