Lines are parallel if they are always the same distance apart (called "equidistant"), and will never meet. They also point in the same direction. Just remember: Always the same distance apart and never …

Parallel and perpendicular lines are two important concepts in geometry. Parallel lines are the lines that never intersect each other. Thus, two parallel lines always maintain a constant distance between …

Two lines are termed as parallel if they lie in the same plane, are the same distance apart, and never meet each other. Perpendicular lines are intersecting lines that always meet at an angle of 90°.

Parallel and perpendicular lines Parallel lines are a fixed distance apart and will never meet, no matter how long they are extended. Perpendicular lines will always cross at right angles.

Jun 14, 2022 · Parallel lines never intersect, while perpendicular lines always intersect at a 90 degree angle. Parallel and perpendicular lines are two key concepts in geometry. Here are the definitions of …

Mar 31, 2018 · When two lines (or two sides of a polygon) are parallel, their slopes will be equal. When two lines (or two diagonals of a polygon) are perpendicular, their slopes will be opposite reciprocals …

Jul 23, 2025 · Parallel lines in geometry are lines that never intersect and are always at the same distance from each other. On the other hand, perpendicular lines are lines that intersect each other …

As with parallel lines, we can determine whether two lines are perpendicular by comparing their slopes. The slope of each line below is the negative reciprocal of the other so the lines are perpendicular.

Aug 20, 2025 · If two lines are parallel, then any line that is perpendicular to one line will also be perpendicular to the other line. Similarly, if two lines are both perpendicular to the same line, then …

Jan 9, 2019 · Parallel lines are lines that will never meet on a plane and they are always at an equal distance apart. Imagine, what would happen if the stair steps were not parallel with each other or …
