1. The problem asks which of the given shapes (A, B, or C) has rotational symmetry. 2. Rotational symmetry means a shape looks the same after being rotated by some angle less than 360 degrees around its center. 3. Shape A has four right triangles arranged so that each points in a different direction: up, left, right, and down. Rotating by 90 degrees will map each triangle onto the position of another, so the shape looks the same after a 90-degree rotation. 4. Shape B has four right triangles arranged pointing up, right, down, and left, but the order is different from A. Rotating by 90 degrees also maps the triangles onto each other, so it has rotational symmetry. 5. Shape C has an uneven arrangement: one triangle up, two triangles right (one small, one large), one left, and one down. Because of the unequal sizes and arrangement, rotating it will not produce the same shape. 6. Therefore, Shapes A and B have rotational symmetry, but Shape C does not. Final answer: Shapes A and B have rotational symmetry.
