Parallel and Perpendicular Lines - Math is Fun
Two lines are perpendicular when they meet at a right angle (90°). To find a perpendicular slope: When one line has a slope of m, a perpendicular line has a slope of −1 m. In other words the negative reciprocal. Find the equation of the line that is. The slope of y = −4x + 10 is −4. The negative reciprocal of that slope is:
What are Perpendicular Lines? Definition, Properties, Examples
In geometry, perpendicular lines are defined as two lines that meet or intersect each other at right angles (90 ∘). The term ‘perpendicular’ originated from the Latin word ‘perpendicularis,’ meaning a plumb line. If two lines AB and CD are perpendicular, then we can write them as AB ⊥ CD.

2024年6月3日 · Find the slope of a line perpendicular to \(3x − 4y = 2\). Solution. We need to rewrite the equation in slope-intercept form. Then we can identify the slope and the slope for a line perpendicular to it.
What are Perpendicular Lines? - DoodleLearning
2023年10月10日 · In mathematics, perpendicular lines are two straight lines that meet or intersect at 90°. This intersection is also called a right angle and is marked by a small square as shown in the figure below: The definition of perpendicular is a straight line at an angle of 90° to a given line, plane, or surface.
Meaning, Examples | Perpendicular Lines Definition - Cuemath
Perpendicular lines, in math, are two lines that intersect each other and the angle between them is 90°. When two lines are perpendicular, we express them using a perpendicular sign ⊥ ⊥. For example, if line ¯¯¯¯¯¯¯¯AB A B ¯ is perpendicular to line ¯¯¯¯¯¯¯¯¯CD C D ¯, we express it as ¯¯¯¯¯¯¯¯¯AB ⊥¯¯¯¯¯¯¯¯¯CD A B ¯ ⊥ C D ¯.
Perpendicular Lines (Geometry) | Brilliant Math & Science Wiki
Two lines are perpendicular or orthogonal if they meet at right angles. For two perpendicular lines, all four angles formed by the two lines are equal to \( 90 ^ \circ\). Two non-vertical lines are perpendicular if and only if the product of their slopes is -1. In other words, the slopes of two perpendicular lines are negative reciprocals of ...
