What Are Perpendicular Lines?
In mathematics, a line is an infinitely long one-dimensional object. It has no start or end, continuing on forever without ever changing direction. More colloquially, a "line" is any straight object, even if it does have an end point. The relationship...
If two lines (a and b) are both perpendicular to a third line (c), all of the angles
formed along the third line are right ...
Let's graph these lines: * I'm using y = mx + b stuff to graph them!
We are asked which of these lines are perpendicular. And it has to be
perpendicular to one of the other lines, you can't be just perpendicular by yourself
Parallel lines never intersect, and perpendicular lines intersect at a 90 degree
angle. Learn how to identify parallel and perpendicular lines.
Perpendicular Lines. more ... Perpendicular Lines. Lines that are at right angles (
90°) to each other. Try for yourself: See: Parallel Lines. Next.
Demonstrates how to determine if slopes are parallel, perpendicular, or neither.
Explains why graphing is not generally helpful for this type of question.
