# Rotating Shapes

Triangle Rotation Activity
Use this worksheet to explore rotations about a point. You may use the slider to change the degree of rotation. You may change the shape of the triangle by moving any of the points. You may move the point of rotation (M) by locating it anywhere on the grid

1. What does changing the value of the slider do to the triangle?
2. How does a 90 degree rotation affect the values of the coordinates of triangle ABC?
3. How does moving point M to (1, 0) effect the values of the coordinates from question 2?
4. Is isometry preserved in all rotations?
