Question

Question 6 (i)
In the given figures below, decide whether l is parallel to m.

Answer 1

When a transversal cuts two lines, such that pairs of interior angles on the same side of the transversal are supplementary, the lines have to be parallel.

${126}^{\circ }+{44}^{\circ }={170}^{\circ }$

l is not parallel to m because sum of interior opposite angles should be ${180}^{\circ }$.
