Identify Translations on a Grid

In this activity, we will learn how to move a shape on a grid following instructions.

We need to be able to read and plot coordinates on a grid where there are both positive and negative numbers. 

When reading and plotting coordinates, remember:

Step 1: Read across the x-axis

Step 2: Read up or down the y-axis

Let's try an example question together. 

Example

Translate this triangle five units to the right and three units down.

Answer

  We need to move the shape corner by corner and then draw the new triangle.

Each of the three points of the triangle will move five places right and three places down.

When the points are drawn together in the new position, the new orientation of the triangle will become obvious.

Now it's time to try some questions like this yourself.
