Question

which lines are parallel lines? *
line a
line b
line c

Explanation:

Step1: Recall parallel lines definition

Parallel lines are lines in a plane that never meet, they have the same slope (or direction).

Step2: Analyze the lines

Line A and Line B have the same slope (they are both slanting in the same direction and will never intersect), while Line C is vertical (different slope/direction from A and B). So Line A and Line B are parallel.

Answer:

Line A and Line B (the checked options: Line A, Line B)
