**What Does Perpendicular Mean** – All good learning starts with vocabulary, so let’s focus on the two most important words in the theorem. Perpendicular refers to the combination of two line segments, rays, lines, or combinations thereof that meet at right angles. A line is perpendicular if it intersects another line, forming right angles.

An angle bisector is an object that cuts another object (angle, line segment) into two equal parts (line, ray, or line segment). A separator cannot split a line because a line is by definition infinite.

## What Does Perpendicular Mean

When we combine the two meanings, we get the concept of a bisector, angle, or line segment that bisects a line, ray, or line segment at a right angle.

; That is, a line dividing the angle into two equal parts, and two right angles are formed by a perpendicular bisector.

When a point lies on the bisector of a line, it is equidistant from the endpoints of the line.

High, right in the middle of your property. They want to broadcast rock music day and night.

Country in the south. Your radio tower is a vertical bisector of the length of your country.

You need to reinforce the tower with wire to keep it from tipping over in strong winds. They are called guy wires. How long should a guy wire be on each side from top to bottom?

Since you have constructed a perpendicular bisector, you don’t need to measure each side. A measure that you can calculate from the geometry will do. Use the Pythagorean theorem for right triangles:

Extends from the top of the tower to the edge of your property. You repeat the process

For each height chosen, cut guy wires of equal length for the left and right sides of your radio tower, since the tower is the perpendicular bisector of your property.

How does it look like? We hope you said side angle side because that’s exactly what it is.

The side angle side postulate states: “If two sides and included angle of one triangle are congruent to two sides and included angle of another triangle, then these two triangles are congruent.”

You can now solve the sentence yourself. You will either sink or swim on this one. Here’s a line segment

What’s yours? Two congruent sides and an included angle, guess what? Indeed, the SAS hypothesis! Hence the line segment

## Parallel And Perpendicular Lines

Note that the theorem is constructed as an “if, then” statement. It immediately suggests that you can write its translation by swapping parts:

When a point is equidistant from the endpoints of a line segment, it lies on the perpendicular bisector of the line segment.

. When you come to a pair of corresponding pages that are not congruent, you will know

Only the points on the vertical segment are equidistant from the endpoints of the line segment. All others end up with a

Perpendicular lines are two distinct lines that intersect at 90Â°. Noticed a commonality between the connecting corners or the letter “L” on your walls? They are called straight lines

We say that a line is perpendicular to another line if the two lines meet at a 90Â° angle

Also known as a right angle, it is marked with a small square between two vertical lines as shown in the figure. Here the two straight lines intersect at right angles and are therefore perpendicular to each other.

Now look at the examples of non-rectangular lines. These lines do not meet at all or intersect at an angle other than 90Â°

### Chords Of A Circle Theorems

In mathematics, perpendicular lines are two lines that intersect at an angle of 90Â°. If two straight lines (overline) and (overline) are perpendicular to each other, we represent this with the notation ( mathbf perp overline}.

We’ve already seen what vertical lines look like. When a figure has an “L” shape, the corresponding angle at the top is a right angle. Vertical lines always intersect, but not all intersecting lines are always perpendicular. The two main properties of perpendicular lines are:

To draw a vertical line, all we need is a ruler, compass or protractor. We will discuss step by step how to draw perpendicular lines with a compass and a protractor. So, for a given line, we can draw perpendicular lines in two ways.

In mathematics, a protractor is considered an important measuring device in the geometry box. This tool not only helps to measure an angle in degrees, but also to draw perpendicular lines. To draw a line perpendicular to point P on the given line, follow the steps given below.

### Basic Biomechanics: Moment Arm & Torque

We can also draw a vertical line with a compass. To draw a line perpendicular to a point P on a line, follow the steps given below.

Two lines are parallel if they are equidistant and never meet, no matter how far they are extended in either direction. Observe the lines below to see the difference between perpendicular lines and parallel lines. In the figure, AB is perpendicular to CD and PQ is parallel to RS.

The symbol ||, used to show that lines are parallel, we express as: PQ || Rs. You can find parallel lines around you. For example crossing zebras on the street or on opposite sides of your controller and many others too! The table below shows the difference between parallel lines and perpendicular lines.

A right angle is the right angle (90Â°) formed when two perpendicular lines intersect.

### Intersecting Parallel And Perpendicular Lines

We use the perpendicular line formula to find the slope of two lines. The formula for the vertical line is defined as the product of two slopes m1 and m2 -1. It is expressed mathematically as (m1Ã—m2 = -1) or m1 = -1/m2.

Perpendicular lines are lines that intersect at right angles (90Â°). Parallel lines are lines that never intersect and are always the same distance apart.

If two straight lines intersect and form an angle of 90Â°, then the two straight lines are perpendicular to each other.

The diagonals of a rhombus intersect at an angle of 90Â°, so you can say that the diagonals of a rhombus are perpendicular to each other. Segment AB is perpendicular to CD because the two angles it makes (shown in orange and blue) are each 90 degrees. Using “perpendicular” as a noun, segment AB can be said to be perpendicular to segment CD of A. Point B is called the base of the perpendicular from A to segment CD, or simply the base of A on CD.

## Lesson Video: Slopes Of Parallel And Perpendicular Lines

In elementary geometry, two geometric objects are perpendicular if they intersect at a right angle (90 degrees or Ï€/2 radians).

A line is perpendicular to another line if the two lines intersect at right angles.

Obviously (1) the first line is perpendicular to a second line when the two lines meet; and (2) at the point of intersection, the right angle on one side of the first line is cut into two congruent angles by the second line. Perpendicularity can be shown as symmetric, meaning that if the first line is perpendicular to a second line, the second line is also perpendicular to the first line. Because of this, we can speak of two lines as perpendicular (to each other) without specifying an order.

Perpendicularity extends slightly to sectors and rays. For example a
