Understanding angles is an important part of Year 7 Math, especially when we talk about the 360-degree rule. This rule helps us see how angles work around a point.

What is the 360-Degree Rule?

The 360-degree rule says that the total of all angles around one point is always 360 degrees.

Imagine you are standing in the middle of a circle. When you look around and turn all the way around, you end up facing the same way you started. This movement is a complete turn, and it's 360 degrees!

Why is This Important?

Knowing the 360-degree rule is super helpful. It lets us find unknown angles and solve problems about angles easily.

For example, if you know two angles at a point, you can easily calculate the third angle.

Example

Let’s say we have two angles that are 130 degrees and 210 degrees.

1. Add the two known angles:
   130 + 210 = 340

2. Subtract from 360 degrees to find the unknown angle:
   360 - 340 = 20

So, the third angle is 20 degrees.

Visualizing with a Diagram

You can picture this with a simple drawing:

• Draw a point in the center of a circle.
• Mark two angles, 130 degrees and 210 degrees.
• The angle left over will fit into the space they created and shows how all the angles add up to 360 degrees.

Real-Life Applications

This rule is not just for schoolwork. Whether you're tilting a picture frame or putting together furniture, the 360-degree rule helps you make sure everything lines up perfectly around the center point.

By understanding and using the 360-degree rule, you can see angles in everyday life, making math a useful tool, not just an idea in a textbook!
