Question

prove that the line l || line n​

Answer 1

Answer:

given,

angle a = angle b

but they are corresponding angle

therefore , line l || m ( two lines are parrallel if the pair of corresponding angle is equal )

for line m and n

angle x = angle y

but they are alternate angle

therefore , line m || n ( two lines are ll if the pair of alternate angle is equal )

Now ,

l ||m

n||m

therefore , l || n ( lines parallel to the same line are parallel to each other )

hence proved ....
