Determine which lines are parallel to one another?
Remember that parallel lines are lines that, if extended, will never intersect.
In diagrams a'+b'+c', all the lines intersect with each other at a certain point, except for diagram d'.
The lines drawn in answer d' will never intersect.
The lines below are not the same size, but are they parallel?
Visual test: If you imagine extending both lines infinitely in both directions, they should never meet. Parallel lines maintain the same distance between them everywhere.
Parallel lines never intersect and run in the same direction. Perpendicular lines intersect at exactly 90° angles, forming perfect right angles.
Yes! Two vertical lines are parallel if they don't intersect. They both go straight up and down, maintaining constant distance between them.
Two horizontal lines at different heights are parallel. They both run left-to-right and will never meet, no matter how far you extend them.
Arrows indicate the direction of the lines. Parallel lines have arrows pointing in the same direction, showing they'll never intersect.
