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

Answer

The shape shown is a square. Rotational symmetry is when a shape looks the same after being rotated by a certain degree around a central point. The 'order' of rotational symmetry is the number of times the shape looks identical during a full 360-degree rotation. For a square, let's consider its properties: 1. It has four equal sides and four equal angles (all 90 degrees). 2. If you rotate a square by 90 degrees around its center, it will perfectly overlap with its original position. 3. If you rotate it by another 90 degrees (total 180 degrees), it again looks the same. 4. Another 90 degrees (total 270 degrees) and it looks the same. 5. Finally, after a full 360-degree rotation, it returns to its original position. Since the square looks identical 4 times during a 360-degree rotation (at 0, 90, 180, and 270 degrees), its order of rotational symmetry is 4. Therefore, the order of rotational symmetry of the given shape (a square) is 4.
