Learn how to find parallel and perpendicular lines using algebra and examples. See how to use slopes, y-intercepts, and negative reciprocals to identify and graph these lines.
Parallel and perpendicular lines are two important types of lines in geometry. Explore the definitions, properties, difference, equations with examples.
Here we will learn about parallel and perpendicular lines including how to show when two lines are parallel or perpendicular, how to calculate the gradient of parallel and perpendicular lines and use this knowledge to calculate the gradient of tangents to circles.
Learn how to identify and differentiate parallel and perpendicular lines in geometry using their properties and equations. See examples of parallel and perpendicular lines in real-life situations and practice questions with answers.
Learn how to construct a line, parallel or perpendicular, to a given reference line and a fixed point, and in the process learn how to utilize the Point-Slope Form and Slope-Intercept Form of a Line.
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 \(−1: m1⋅m2=−1\).
1 mar 2022 · This article will review the definitions of parallel and perpendicular lines as well as determine equations for parallel and perpendicular lines. By the end, we’ll be able to describe any two lines as parallel, perpendicular, or neither.
