Question

which two lines are parallel? (hint: use the angle relationships not whether they look parallel!) lines n and p lines m and n lines m and p

Explanation:

Step1: Use the property of supplementary angles

For two parallel lines cut by a transversal, consecutive interior angles are supplementary ($180^{\circ}$).
For line M with an angle of $70^{\circ}$, its consecutive interior angle (if parallel) should be $180 - 70=110^{\circ}$.

Step2: Check the angles

Line P has an angle of $110^{\circ}$. So, lines M and P follow the consecutive - interior - angles - supplementary property for parallel lines.

Answer:

Lines M and P
