Question

Based on the diagram below, which is notdrawn to scale, which two lines are parallel?a65°110°70°b115°Line ais parallel toLine c:: Line b:: Lined:: Line e

Answer 1

For two lines to be parallel, they have to form the same angle when crossing the same line.

Now, M and N are alternate interior angles and

`\begin{gathered} M+65^(\circ)=180^(\circ) \\ M=115^(\circ) \end{gathered}`

Hence, line c and line a are parallel.
