  1. Perpendicular and Parallel - Math is Fun

    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 …

  2. Parallel and Perpendicular Lines - Definition, Properties, Examples

    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°.

  3. Parallel versus Perpendicular - MATHguide

    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 …

  4. Parallel and Perpendicular Lines - GeeksforGeeks

    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 …

  5. Parallel and Perpendicular Lines - Science Notes and Projects

    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.

  6. 4.2.6: Parallel and Perpendicular Lines - Physics LibreTexts

    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 …

  7. Parallel and perpendicular lines - KS2 Maths - Year 3 - BBC

    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.

  8. Parallel and Perpendicular Lines | College Algebra Corequisite

    Unlike parallel lines, perpendicular lines do intersect. Their intersection forms a right or 90-degree angle. The two lines below are perpendicular. Perpendicular lines. Perpendicular lines do not have the …

  9. Parallel and Perpendicular Lines – Definition With Examples

    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 …

  10. Difference Between Perpendicular and Parallel Lines

    Dec 4, 2025 · Mathematically speaking, when we denote two lines as being perpendicular (often represented with the symbol “⊥”), we’re highlighting their unique property: if line A intersects line B at …
