Question

Do parallel lines meet at a 90 degree angle?

Answer 1

Parallel lines never meet, and perpendicular lines intersect at a right angle. and do not intersect in this image, but if you imagine extending both lines, they will intersect soon. So, they are neither parallel nor perpendicular.

Answer 2

No. Parallel lines never cross. An example would be railroad tracks. They never cross even though they turn in different directions.
