# What is an example of a perpendicular line?

## What is an example of a perpendicular line?

Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle. The symbol used to denote two perpendicular lines: ⊥ ⊥ .

## Does perpendicular mean straight?

adjective. vertical; straight up and down; upright. Geometry. meeting a given line or surface at right angles.

What is perpendicular sides?

The word “perpendicular” means “at right angles” and this is because when two lines meet, they form right angles. Perpendicular lines can face in any direction such as up and down, crossways, and side-to-side. They also do not have to be standing straight up from the bottom or side of the page.

What does perpendicular mean in physics?

The term perpendicular describes a pair of lines or planes that intersect each other at a 90 degree angle. In science and engineering, a line perpendicular to another line or a plane is often referred to as being normal to the plane, or simply called the surface normal.

### What does perpendicular mean on a graph?

If two non-vertical lines in the same plane intersect at a right angle then they are said to be perpendicular. Horizontal and vertical lines are perpendicular to each other i.e. the axes of the coordinate plane.

### What is perpendicular in physics?

When was perpendicular first used?

Perpendicular was the prevailing style of Late Gothic architecture in England from the 14th century to the 17th century.

How do you find perpendicular?

Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6. Rearranged, it is –x/2 + y = 6.

#### What does perpendicular mean in geometry?

Perpendicular lines are lines, segments or rays that intersect to form right angles. The symbol ⊥ means is perpendicular to . In the figure, PR⊥QS. The right angle symbol in the figure indicates that the lines are perpendicular.

#### What does perpendicular mean ks2?

When two lines are perpendicular, they are at right angles to each other. All of these diagrams show pairs of lines that are perpendicular to each other.

What does perpendicular mean in slope?

opposite reciprocals
Perpendicular lines are lines that intersect at right angles. If you multiply the slopes of two perpendicular lines in the plane, you get −1 . That is, the slopes of perpendicular lines are opposite reciprocals .

What does perpendicular mean in algebra?

If two non-vertical lines in the same plane intersect at a right angle then they are said to be perpendicular. Horizontal and vertical lines are perpendicular to each other i.e. the axes of the coordinate plane. Example. Compare the slope of the perpendicular lines.

## Is perpendicular to explain?

A line is said to be perpendicular to a plane if it is perpendicular to every line in the plane that it intersects. This definition depends on the definition of perpendicularity between lines. Two planes in space are said to be perpendicular if the dihedral angle at which they meet is a right angle (90 degrees).

## What is the definition of Perpendicular in math?

Perpendicular means “at right angles”. A line meeting another at a right angle, or 90° is said to be perpendicular to it. In Coordinate Geometry (where all points are described by two numbers which specify the x and y location of the point), a line is perpendicular to another if the slopes of the lines have a certain relationship.

What makes two lines perpendicular?

Two lines are perpendicular if they intersect at right angles. In the coordinate plane, you can represent lines in slope-intercept form as and two lines will be perpendicular if . You could also represent them in parametric form as where p is a point and v is a direction vector.
