Question

two lines are parallel if they: never intersect. intersect in 90 degree angles. eventually intersect.

Explanation:

Step1: Analyze the definition of parallel lines

Parallel lines are defined as lines in a plane that do not meet; they are always the same distance apart.

Step2: Check each option

• For the option "never intersect", it aligns with the definition of parallel lines.
• For the option "intersect in 90 - degree angles", this is the definition of perpendicular lines, not parallel lines.
• For the option "eventually intersect", parallel lines by definition do not intersect at all, let alone eventually.

Answer:

A. never intersect.
