Let's start with the basics of angles. Angles are essentially the slantiness of something .

Below are examples of what angles look like. You don't need to know the names of the types of angles, but that they:

• Measure the degree of things – look at the shaded areas.
• A full angle is 360 and that's the "whole circle".
• They are a fraction of the whole circle.

Within abstract reasoning angles appear quite a bit:

• In shapes – they are a component of a shape transformation. Think about a rhombus (diamond) to a kite.
• In direction and positioning – if you've got something that's moving anticlockwise on each corner of a square, you've got an angle movement of 90 degree each time starting at North West.

In angle transformations we discover a** new type** – when angles change their degree e.g. increasing degree, decreasing degree, repeating degree.

Angles themselves can also form patterns such as:

• Increasing or decreasing by x degrees each time for example, increasing by 45 degrees for each movement or reducing by 90 degrees each time.
• They can fractionalize a full image with their angles by increasing or decreasing the portion available for viewing.

Let's illustrate this with some examples to get your understanding up:

Example 3

Key Rules to remember:

• Increasing or decreasing by x degrees each time for example, increasing by 45 degrees for each movement or reducing by 90 degrees each time.
• They can fractionalize a full image with their angles by increasing or decreasing the portion available for viewing.
