# What are the Basic Elements in Geometry?

## Tha Basic Elements of Geometry

The Basic Elements of Geometry help to compose shapes and other aspects of geometry by using these basic items.

**Point ** - a point is represent by a dot that you can see and draw on a piece of paper. In reality a point is minuscule and is a single exact location

**Line** - a line is represented in geometry by a straight edge with arrows pointing in opposite directions signifying that the line continues on forever in those directions.

**Line Segment** - a straight edge that has two endpoints and stops at those endpoints or points.

**Ray** - a straight edge that has one endpoint and one arrow that signifies that the edge continues on forever in that single direction.

## Basics of Geometry

## How to Label the Elements

We label the element using symbols of Geometry

A point is ussually labeled with a single capital letter. When we see a single letter it is referring to specific point.

A lines is labeled with two points that define the line. When writing the notation we write the two point letter next to each other and draw a line symbol above them.

A line segment is labeled in the same way with the endpoints serving at the point of distinction.

One important item to note in a ray is that the labeling should always start with the point that is the endpoint of the ray.

Notice how each geometric element is written out in a problem or solution. This is important for more complicated geometry, so it is important to know from the beginning what the symbols mean and how to write them.

## How do we use those elements?

We use the geometric elements everyday without always realizing it. Below I have drawn a triangle. Three line segments and three points (otherwise known as vertices) work together to create a triangle.

When two line segments, rays, or lines meet at a point it creates a vertex (plural vertices).

## Geometry Elements work Together

## Geomtery

Geometry can be broken down into simple pieces as long as we understand the basics. A Point, line, line segment, and ray are some of the basic elements in Geometry.

## Comments

Tnx For The Info.

thanks

Excellent basic layout! When I learnt geometry.. this was the first class!

Basics are the most essential topics to learn in a topic. They help in clearing all concepts later on and developing a strong base over the topic

nice share!!

Where were you when I was learning geometry? They made it too hard way back then!
