Hello, in this video I talk about 2 different types of lines: parallel and perpendicular. For parallel lines, the slopes are the same because these are lines that never intersect at any point.

The Mathematics Teacher (MT), an official journal of the National Council of Teachers of Mathematics, is devoted to improving mathematics instruction from grade 8-14 and supporting teacher education ...

Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to bottom, perpendicular to the horizon, with undefined slope and equation x = k.

Higher - The gradients of two perpendicular lines will always multiply to make –1. Make sure you are familiar with finding the equation of a line and calculating gradient to understand equations of ...

To become proficient in geometry, students must learn about a variety of lines and angles. One important concept is understanding parallel, perpendicular, and intersecting lines. These lines are basic ...

Susanna Post explains a strategy for remembering the difference between parallel and perpendicular lines. In addition, she demonstrates the meanings of parallel and perpendicular lines by showing real ...
