When we talk about rotations in math, especially in Year 8, the direction you turn is really important. This affects how a shape changes. There are two main ways to turn: clockwise and counterclockwise (or anticlockwise).
1. Clockwise Rotation:
This is when a shape turns the same way as the hands of a clock.
Imagine you have a triangle. If you rotate it 90 degrees clockwise around a point, each corner of the triangle will move to the right and down.
2. Counterclockwise Rotation:
This direction is the opposite. Here, the shape turns the other way around.
So, if you take that same triangle and rotate it 90 degrees counterclockwise, the corners will move to the left and up.
Why Is This Important?
The final spot of the shape changes a lot depending on the direction you turn it. For example:
Understanding with a Clock:
Think about a clock. Turning from 12 to 3 is a clockwise rotation. But turning from 12 to 9 is a counterclockwise rotation.
Even a small change in how you turn can lead to different results. So, always remember to check which way you are rotating!
