Rotations

Below you see a computer-generated rotation. When you move the green slider, it will make the transformed shape rotate by the given degrees. The table to the right of it shows the coordinates of the original shape (Point A, Point B, and Point C) and the transformed shape (Point A', Point B', and Point C'). Play around with the slider and see if you can find any patterns with the points as you rotate. You can also drag Point A, Point B, and Point C around and see how that affects the coordinates in the table When you are done investigating, answer the questions below. For each, there is only one answer, and you leave the wrong answers blank. You should check your answers after each!

Investigating Rotations
