Question

Is each pair of lines parallel, perpendicular, or neither?

Answer 1

The first pair forms a 90° angle therefore the lines are perpendicular.

The second lines are straight that it's obviously clear they will never meet meaning they are parallel

the third lines are neither perpendicular nor parallel.

Answer 2

1. perpendicular

2. parallel

3. neither

Explanation:

The first set of lines are perpendicular because they intersect each other at a right angle.

The second set of lines are parallel because they never cross.
