# Perpendicular in Geometry: What It Is and How It's Used

One of the most basic concepts in geometry is perpendicular. Perpendicular lines, angles, and shapes are used in a variety of ways to solve geometry problems. In this article, we'll discuss what perpendicular is and how it can be applied to various geometric scenarios.

## What is Perpendicular?

At its core, perpendicular means "at right angles." This means that two lines or shapes are perpendicular if they intersect at a 90° angle. A common way to indicate that two lines are perpendicular is to draw a small square at the point where they meet. If you were to draw a circle around those two lines, the square would be located at the exact center of that circle.

## How Is Perpendicular Used?

Perpendicular is used in many different ways in geometry. For example, if you wanted to calculate the distance between two points on a graph, you could use perpendicular lines and angles. You could also use it for calculating distances between parallel lines or for determining the area of certain shapes. Additionally, it's often used when solving problems involving triangles or quadrilaterals since those shapes often contain right angles or other forms of perpendicularity.

One of the most common ways that perpendicular is used is in constructing parallelograms. By drawing two sets of parallel lines and then connecting them with pairs of perpendicular lines, you can construct a parallelogram with ease. Similarly, using pairs of perpendicular bisectors can help you construct other types of quadrilaterals such as squares and rectangles.

## Conclusion:

Perpendicularity plays an important role in many aspects of geometry and math as a whole. Knowing how to identify when something is at right angles—or when something isn't—can help students better understand various geometric concepts as well as build stronger problem-solving skills. Understanding how to apply this concept correctly can lead to success in any field that requires geometry knowledge such as architecture or engineering. With these tools under your belt, you'll be able to tackle any geometry problem that comes your way!

## FAQ

### What does perpendicular mean simple definition?

Perpendicular simply means "at right angles." This means that two lines or shapes are perpendicular if they intersect at a 90° angle. A common way to indicate that two lines are perpendicular is to draw a small square at the point where they meet.

### What is a perpendicular example?

A common example of perpendicular lines is a set of four walls that form a room. Each wall is at right angles to the other three walls, forming four perpendicular lines. Additionally, any two sides of a square are also perpendicular to each other since they meet at right angles.

### How do you explain perpendicular to a child?

Perpendicular means "at right angles." You can explain this concept to a child by showing them two straight lines that intersect at a 90° angle. For example, you could point out how the walls of a room are perpendicular to each other since they form four corners at right angles. Or, you could draw a picture of a square and explain that any two sides of a square are also perpendicular to each other. This way, they can visually understand how perpendicular works.
