A shape is drawn on a centimetre grid. Write down the order of rotational symmetry of the shape. The shape drawn is a square.

Answer
The shape shown on the centimetre grid is a square. To find the order of rotational symmetry, we need to determine how many times the square looks exactly the same when rotated by less than 360 degrees around its center. A square has 4 equal sides and 4 equal angles (90 degrees each). 1. If you rotate a square by 90 degrees (a quarter turn), it looks exactly the same as its original position. 2. If you rotate it by 180 degrees (a half turn), it also looks exactly the same. 3. If you rotate it by 270 degrees (three-quarter turn), it still looks exactly the same. 4. If you rotate it by 360 degrees (a full turn), it returns to its original position, which always counts as one instance of symmetry for any shape. Since the square looks the same at 90, 180, 270, and 360 degrees (relative to its starting position), it has an order of rotational symmetry of 4.
