Transforming shapes


Rotate a shape with and without a centre of rotation. If the centre is given, then it will be at the centre of the shape or on one of its vertices. Use 90, 180, 270 degrees. Tracing paper is always permissible. Describe a rotation including finding the centre of rotation by trial and improvement. Understand that the image preserves length and angles. Do not use a coordinate grid, but only square paper.
