Perpendicular lines are those that form a right angle at the point at which they intersect. Parallel lines, though in the same plane, never intersect.

Perpendicular lines are lines that intersect one another at a 90 degree angle. If two lines are perpendicular, then multiplying the slopes of the two lines together equals -1.

One common example of perpendicular lines in real life is the point where two city roads intersect. When one road crosses another, the two streets join at right angles to each other and form a cross-type pattern. Perpendicular lines form 90-degree angles, or right angles, to each other on a two-dime

In Euclidean geometry, two perpendicular lines intersect at a single point called the intersection. If the two lines are y = ax + b and y = cx + d, then their intersection has x coordinate (d-b)/(a-c) and y coordinate [a(d-b)/(a-c) + b].

Perpendicular parking is done at a 90-degree angle to the curb. Perpendicular spaces make maneuvering the vehicle more difficult than angle parking, but the procedure requires fewer steps than parallel parking.

A triangle can have two perpendicular sides. If two sides are perpendicular, the angle they form is a right angle. A triangle can have only one right angle.

The phrase "perpendicular lines intersect to form right angles" can be turned into an if-then statement by saying: If perpendicular lines intersect, then the lines form right angles. It can also be phrased as: If two lines form right angles, then the lines are perpendicular.

A line that is perpendicular to the x-axis has an undefined slope. All of the points on such a line have the same x-coordinate. If the value of x never changes, then the formula for slope, (y2 - y1)/(x2 - x1), has a denominator of zero, which is mathematically undefined.

For each vector, the angle of the vector to the horizontal must be determined. Using this angle, the vectors can be split into their horizontal and vertical components using the trigonometric functions sine and cosine. The horizontal components for the vectors are solved separately from the vertical

A perpendicular bisector is a line that cuts across the midpoint of a given line segment at a 90-degree angle. It divides the line segment into two equal parts. A common method for drawing perpendicular bisectors uses a compass and straight edge or ruler.
