Recall our triangle from 3.1.1 Vertex Model of Points. We can represent the three corners of our triangle with column vectors.
Create a second triangle by shifting the vertices to the left by one unit and down by two units using 4.2 Column Vector Addition.
Solution. Let's create the vector to shift the triangle.
Now, we can shift our vertices. If we let , we see:
If we graph these points, we indeed see that the vertices were shifted left one and down two.
