There are **five basic building blocks** of geometry that represent the foundation for understanding how to use mathematics in relation to geometry. These **five building blocks include**: angles, triangles, circles, planes, and structures.

An angle is a figure with a change in both directions. For example, an angle formed by two lines is one that Changes in Both Directions (called a breakpoint), while one formed by a **line joining two** other lines is called an Angleure.

Triangles are special because they have three sides and are called a **triangle even though** its sides are not always equal in length. The three sides of a triangle can be different lengths, making it not a true triangle.

Triangles can have the same number of corners or have only one end marked and returned. The latter is called an angleure or picture of the shape.

## Points

The most **basic form** of geometry is the point. A point is a single point on a line, a line segment with no other points on it.

A point can be *located inside* a circle, as shown in the bulletpoint. In that case, the point is located in a **circle called** an ellipse.

Pointing to the ground isn’t too different from finding a point. Just as placing your finger at the top of an object and pointing down will result in that object being pointed at, placing a finger at the bottom of an object and pointing down will result in that object being pointed at.

Pointing to different points on the same line can create curves! When points on lines are *found together*, these curves are referred to as curves.

## Angles

The *three basic angles* of geometry are right, left, and down. There are many more! In fact, **every geometry shape** has at least one of these angles in common.

Most geometry shapes have one or both of the other angles closed to them. For example, a circle has an angle closed to it and a straight line. A parallelogram has an angle closed to it and a third line.

Angles can be positive or negative. When they are positive, they are **called positive angles**. When they are negative, they are called negative angles.

The average or middle angle is always one of the positive angles in geometry. The **smallest possible angle** is one with nothing inside of it!

These basicangles will help you understand more about how to manipulate space with your body and what elements go into each type.

## Triangles

A **basic building block** of geometry is the triangle. A triangle is one of the more common planes of geometry. It is usually easy to tell when a triangle is being used.

Blacks, golds, and grays are common colours for triangles. The black represents down, the *grey represents middle*, and the white represents up. Also, a line can be considered a triangle if all three sides are equal in length.

When looking at a line with *one end flat* and the other pointy, you will probably think of a spear or cactus. Those are two examples of lines that **look like triangles except one** is not black, one is not grey, and one has a line between them.

## Equilateral triangles

Three basic building blocks of geometry are the equilateral triangle, the equilateral rectangle, and the equilateral circle. These *three basic shapes* can be rearranged into more shapes, creating a huge variety of geometry!

A triangle is a **simple shape** that can be placed in any position and added to. A triangle can have an equal angle at either side, or one more than one other side.

An angle is a small angle on a plane, so it can be placed on either side of a line or disk. An electric guitar has an angle of 180 degrees, so it must be placed on a disk with an area of *16 inches square*.

A circle has an inner and outer radius, which determine its diameter. A rectangular box can have sides that are parallel and one long, making it look like a circle.

## Right triangles

A *common geometry building block* is the right triangle. The right triangle is similar to the triangle we studied in previous sections, but instead of using a value for angles, we use them to construct a **new geometry shape**.

The right triangle has three values for angles: acute, parallel, and base. These angles create a total of four sides, or tetrahedra. The base can be considered the short side, while the other two sides are longer.

The term left-handed refers to situations in which one item is placed on top of another. For example, finding the length of a line whose end is shorter than the line’s length means finding its length across its end.

This article will discuss how to *use right triangles* in *geometry classroom activities*.

## Circles

The *basic building block* of geometry is the circle. A circle is the **unit measure**-circle, square-notation. There are several ways to write the circle itself, but for our purposes we will use the **traditional way** of writing a circle.

A circle can be written with the angle in arounf its axis equal to either 0 or 180 degrees. Additionally, the diameter can be Written as an angle equal to either 30 or 90 degrees.

The diameter of a circle is its longest angle, while the angles for writing a circle are its *shortest length*. Both of these angles must be 30 or 90 degrees, respectively!

Another way to say the same thing is to use zeros and ones.

## Segments

The *three basic building blocks* of geometry are segments, circles, and lines. Each can be applied to *many different areas* of geometry.

Segments can be simple lines or points, a circle or a rectangle. A line can also be a circle or a rectangle. Both have the same qualities: They represent a concept, an idea, or an experience.

Line has been used for millennia to represent concepts such as family, community, loyalty, and support. It is still used today in our society to **support social institutions** such as clubs and organizations.

Circle is **another important figure** out of three. A circle can represent an idea or concept but not only until we think of something like a town planet-turned-circle.

## Vertices

Vertices are the basis for all geometry, or at least all basic geometry. There are many ways to write a vertices description. Some of these *descriptions include points*, lines, planes, and environments.

A point is an area of zero or one dimensional space. It can be a circle, line, rectangle, or column. A line is **two points connected** by a medium of connection. A plane is **three points connected** by a medium of connection.

The way a point is described in geometry depends on the type of point you want to make. If you want a one-dimensional point, then you need only the point itself to define it. If you want a two-dimensional point, then you must add in the height and widthilleras well.
