The construction of perpendicular lines is really easy once you know how to do it! We cover two important and easy methods of constructing perpendicular lines here:

Using a ruler, draw a straight line on paper that is parallel to the top and bottom of the paper and is 10 cm long. Draw a point above your line that is exactly halfway along the line.

Generally, the standard phrase used to represent to represent two perpendicular lines is AB ⊥ CD. In this iteration, it shows that the AB line is perpendicular to the BC line.

If your line has a positive slope, its perpendicular line should have a negative slope. That’s because it is the “negative reciprocal” of your positive line’s slope.

There are specific rules that dictate the slopes of perpendicular lines. They are opposite and reciprocal to one another. If you need to find the slope of the line perpendicular to an equation, you’ll need to find the opposite reciprocal.

Perpendicular lines can be found all around us in everyday life. Here are just a few of the perpendicular lines examples you’ll see around you in real life:

Now you know the perpendicular meaning in math. Below, we fully define perpendicular lines and what makes them different from other line types, such as parallel lines.

While it might seem complex to find the slope of a perpendicular line, it’s actually straightforward with this technique: if two lines have slopes m1 and m2. They are perpendicular if m1× m2 = -1. The minus sign denotes the right angle formed by the two lines.

In this article, we’ll cover the perpendicular definition and the symbol of perpendicular lines, share perpendicular lines examples and provide practice questions so you can test yourself.

Perpendicular sides are sides in a shape that meet at a right angle (AKA a perpendicular angle). Perpendicular sides are formed of perpendicular lines, but they form a closed shape. Not all perpendicular lines need to form a closed off shape.

The perpendicular symbol is ⊥. This symbol represents a set of perpendicular lines. If we want to express this more comprehensively, we could say that ‘m’ and ‘n’ are two lines that intersect one another at right angles, therefore they are perpendicular to one another. They can therefore be represented with the expression m⊥n. The symbol is displayed this way to show the point at which the two perpendicular lines intersect as the “foot of the perpendicular”.

The perpendicular meaning is a 90° angle (aka a right angle) that is created as the result of two lines, planes or vectors intersecting. The perpendicular line and perpendicularity are essential concepts when it comes to mastering trigonometry, geometry, calculus and other key math disciplines.

You can use a protractor to work out the right angle at these perpendicular line intersects, then draw the line from point A to point B to reveal a right-angled triangle.

The perpendicular lines definition is two lines that intersect with one another, creating a right angle (an angle that is 90°). One perpendicular line is a line that intersects another perpendicular line at a right angle, meaning they are perpendicular to one another. Perpendicular lines essentially cross paths with one another at a specific angle that then creates a right angle.

Perpendicular lines and parallel lines are two different concepts in geometry, and they cannot both be true of the same two lines. Perpendicular lines will always intercept, and at that interception, they will always create a right angle, also known as a perpendicular angle. Perpendicular lines do not have equal slopes. They are inverse reciprocals, meaning that eventually, the two lines can and will intersect at 90°.

Drawing a perpendicular line using a protractor is arguably the easiest method of drawing a perpendicular line. Simply follow these quick, straightforward steps:

The definition of perpendicular lines informs many different math concepts, plus their properties make many different types of problem solving easy. That’s because you can quickly and easily understand if two lines are perpendicular, often just by looking at them. If you can’t tell by looking, you can use a protractor.

Parallel lines are equidistant to one another and can never, ever meet – even if they go on infinitely. This is because they are always the same distance apart because they have the same slope, therefore there is never a meeting point between the two. Parallel lines have equal slopes with a constant distance between them.

All perpendicular lines will be the inverse of the original line’s slope. You can calculate this slope by transforming a linear equation into slope-intercept form. Equally, by taking its negative reciprocal, you can also calculate the slope of a perpendicular line.
