1) Rotation A rotation is spin or turn. You simply move it around.

1) Rotation Practice: 1) Draw a triangle and rotate it 180°. 2) Draw a rectangle and rotate it 90° 3) Draw a ray and rotate it 270° To complete a rotation, you need to pick a vertex to be your rotation point.

You reflect it around a line of symmetry.
