Before you learn how to add and subtract fractions you need to understand some key vocabulary first.

Adding and Subtracting Fractions with the Same Denominator

Let’s start by reviewing the difference between a numerator and a denominator:

How to Add and Subtract Fractions with Like Denominators

In the above example, 1/5 and 3/5 have common denominators (both equal 5). To add them together, you just have to add the numerators together and leave the denominator alone as follows:

Since 4/5 can not be simplified any further, you can conclude that:

1/5 + 3/5 = 4/5

But what about when the denominators are not the same?

Adding and Subtracting Fractions with Unlike Denominators

How do you add and subtract fractions when the denominators are different?

You can use the following 3-step process for adding and subtracting fractions (with and without common denominators).

Subtracting Fractions with Unlike Denominators Example

STEP ONE: Get a common denominator.

STEP TWO: Add or subtract the numerators.

STEP THREE: Simplify the result if needed.

Notice that 3/27 can be simplified, since the numerator and denominator are both divisible by 3.

And that’s all there is to it!

Geometry Transformations: Rotations 90, 180, 270, and 360 Degrees!

April 30, 2020

Performing Geometry Rotations: Your Complete Guide

The following step-by-step guide will show you how to perform geometry rotations of figures 90, 180, 270, and 360 degrees clockwise and counterclockwise and the definition of geometry rotations in math! (Free PDF Lesson Guide Included!)

Welcome to this free lesson guide that accompanies this Geometry Rotations Explained Video Tutorial where you will learn the answers to the following key questions and information:

What is the geometry rotation definition and what is the definition of rotation in math?
How to perform clockwise and counterclockwise rotations
How can you rotate a triangle about the origin?
Several geometry rotation examples

This Complete Guide to Geometry Rotations includes several examples, a step-by-step tutorial, a PDF lesson guide, and an animated video tutorial.

*This lesson guide accompanies our animated Geometry Transformations: Rotations Explained! video.

Rotation Geometry Definition

Before you learn how to perform rotations, let’s quickly review the definition of rotations in math terms.

Rotation Geometry Definition: A rotation is a change in orientation based on the following possible rotations:

90 degrees clockwise rotation
90 degrees counterclockwise rotation
180 degree rotation
270 degrees clockwise rotation
270 degrees counterclockwise rotation
360 degree rotation

Note that a geometry rotation does not result in a change or size and is not the same as a reflection!

Clockwise vs. Counterclockwise Rotations

There are two different directions of rotations, clockwise and counterclockwise:

Clockwise Rotations (CW) follow the path of the hands of a clock. These rotations are denoted by negative numbers.

Counterclockwise Rotations (CCW) follow the path in the opposite direction of the hands of a clock. These rotations are denoted by positive numbers.

Clockwise rotations are denoted by negative numbers.

Counterclockwise rotations are denoted by positive numbers.

Note that the direction of rotation (CW or CCW) doesn’t matter for 180 and 360-degree rotations, since they will both bring you to the same spot (more on this later).

Geometry Rotation Notation

Note that the following notation is used to show what kind of rotation is being performed.

For example, Figure 1 is a rotation of -270 degrees (which is a CW rotation).

Now you are ready to try a few geometry rotation examples!

Geometry Counterclockwise Rotation Examples

Example 01: 90 Degrees Counterclockwise About the Origin

Since 90 is positive, this will be a counterclockwise rotation.

In this example, you have to rotate Point C positive 90 degrees, which is a one quarter turn counterclockwise.

Point C lays in the 1st quadrant.

To perform the 90-degree counterclockwise rotation, imagine rotating the entire quadrant one-quarter turn in a counterclockwise direction.

Note the location of Point C’, the image of Point C after a 90-degree rotation.

And this process could be repeated if you wanted to rotation Point C 180 degrees or 270 degrees counterclockwise:

This example should help you to visually understand the concept of counterclockwise geometry rotations. Next, you will learn the rules for performing counterclockwise rotations.

>>> Before you move on, take some time to visualize what rotations look like on the coordinate plane.

<><><>

Counterclockwise Rotation Rules

You can use the following rules when performing any counterclockwise rotation.

By applying these rules to Point C (3,6) in the last example (Figure 2), you can see how applying the rule creates points that correspond with the graph!

Left: replace x with 3. Right: replace x with -9

These points should look familiar! They are the points that you plotted in the last example!

Geometry Clockwise Rotation Examples

Example 01: 90 Degrees Clockwise About the Origin

Since the rotation is 90 degrees, you will be rotating the point in a clockwise direction.

Now imagine rotating the entire 4th quadrant one-quarter turn in a clockwise direction:

Note the location of Point D’, the image of Point D after a -90-degree rotation.

And this process could be repeated if you wanted to rotation Point D -180 degrees or -270 degrees counterclockwise:

This example should help you to visually understand the concept of clockwise geometry rotations. Next, you will learn the rules for performing clockwise rotations.

>>> Before you move on, take some time to visualize what rotations look like on the coordinate plane.

<><><>

Clockwise Rotation Rules

You can use the following rules when performing any clockwise rotation.

By applying these rules to Point D (5,-8) in the last example (Figure 3), you can see how applying the rule creates points that correspond with the graph!

These points should look familiar! They are the points that you plotted in the last example!

More Geometry Rotations Examples

Example 01: Rotate a Line Segment 90 Degrees Clockwise

You can perform this rotation by using the rules or by doing a visual rotation as follows:

Example 02: Rotate a Triangle 180 Degrees

Note that it doesn’t matter which direction go (CW or CCW) for 180 degrees rotations, since you will end up in the same position either way!

You can perform this rotation by using the rules or by doing a visual rotation as follows:

Multiplying Polynomials Explained!

Before you learn how to multiply polynomials, let’s quickly review some important information:

The Distributive Property

Definition: The distributive property allows for you to multiply a sum by multiplying each term separately and then add all of the products together.

If you understand the distributive property, you will be able to multiply polynomials with ease.

Multiplying Polynomials Examples

Multiplying Polynomials Example 1: Multiplying by a Monomial

In this first example, you will be multiplying a monomial by a trinomial. You can think of this as multiplying one “thing” by “another thing” as follows:

This is where using the distributive property (or distributive method) will help you!

To multiply these polynomials, start by taking the first polynomial (the purple monomial) and multiplying it by each term in the second polynomial (the green trinomial).

This can be done by multiplying 4x^2 by the first term of the green trinomial (Figure 1), then by the second term of the green trinomial (Figure 2) and finally by the third term of the green trinomial (Figure 3).
