Question

complete the sentence.
parallel lines are coplanar lines that ______
share an endpoint
never intersect
intersect at right angles
intersect at non - right angles

Explanation:

To determine the correct completion for the sentence about parallel lines, we analyze each option:

• "Share an endpoint": Lines that share an endpoint are intersecting (or adjacent) lines, not parallel. Parallel lines do not share endpoints.
• "Never intersect": By definition, parallel lines are coplanar lines that do not intersect, no matter how far they are extended.
• "Intersect at right angles": Lines that intersect at right angles are perpendicular lines, not parallel.
• "Intersect at non - right angles": Parallel lines do not intersect at all, so this option is incorrect.

Answer:

never intersect
