1. The problem asks for the order of rotational symmetry of a shape that looks like a three-pointed star or propeller. 2. Rotational symmetry order is the number of times a shape fits onto itself during a full 360-degree rotation. 3. Since the shape has three identical triangular parts evenly spaced around the center, each part is separated by an angle of $\frac{360^\circ}{3} = 120^\circ$. 4. This means the shape maps onto itself 3 times during a full rotation. 5. Therefore, the order of rotational symmetry is 3. Final answer: The shape has rotational symmetry of order 3.
