Question

In 1–2 sentences, define parallel and perpendicular lines and explain the difference between the two. Make your answer simple, coherent, and intended for ninth grade.

Answer 1

Parallel lines are two lines that run in the same direction and never meet, no matter how far they are extended. Perpendicular lines, on the other hand, intersect at a right angle (90 degrees), forming a square corner. The key difference is that parallel lines never cross, while perpendicular lines always do at a specific angle.
