Question

If M ⊥ N and L ∥ M, then _____

Answer 1

L ⊥ N

Explanation:

Since M and N are perpendicular, and L is parallel to M, anything that's perpendicular to M is also perpendicular to L. In fact, since we have parallel lines, we now have many sets of congruent angles, but the only ones we know the actual measurements of are the right angles from the perpendicular lines.
