Parallel and perpendicular lines are two important types of lines in geometry. Explore the definitions, properties, difference, equations with 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°. Let us learn more about parallel and perpendicular lines in this article.
a vertical line is parallel to another vertical line. a vertical line is perpendicular to a horizontal line (and vice versa). Summary. parallel lines: same slope; perpendicular lines: negative reciprocal slope (−1/m)
Parallel lines are the lines that never intersect each other and are equidistant. Learn about parallel lines, transversal, properties, equations, examples & more.
Parallel Lines. Lines are parallel if they are always the same distance apart (called "equidistant"), and will never meet. Just remember: Always the same distance apart and never touching. The red line is parallel to the blue line in each of these examples: Example 1.
Perpendicular lines are lines in the same plane that intersect at right angles (\(90\) degrees). Two nonvertical lines in the same plane, with slopes \(m_{1}\) and \(m_{2}\), are perpendicular if the product of their slopes is \(−1: m1⋅m2=−1\).
In this tutorial, we’ll look at an important concept – parallel and perpendicular lines, in the context of analytic geometry (or coordinate geometry). So let’s get started. Two lines are said to be parallel if they are in the same plane and never intersect.
