Question

In figures 12a and12b, lines l and m are cut by a transversal t. find whether l is parallel to m or not​

Answer 1

No because parallel lines do not have common point point and if we check 70 +55 we get 125 that is linear pair forms 180 degrees

Answer 2

Answer:

No, it's not parallel

Step-by-step explanation:

$70 + x = 180 \\ x = 180 - 70 \\ x = 110$

$55 + x = 180 \\ x = 180 - 55 \\ x = 125$

So, 70 is not equal to 125 by using alternative interior angles
