- For part (a), shade the triangles such that each grid has a vertical line of reflection symmetry through its center, but no rotational symmetry. This means the left and right halves mirror each other, but rotating the grid by 120° or 240° does not produce the same pattern.
- For part (b), shade the triangles so that rotating the grid by 120° or 240° around its center produces the same pattern, but there is no line of reflection symmetry. The shaded triangles should be arranged in a cyclic pattern around the center.
- For part (c), shade the triangles so that the pattern has both reflection symmetry (e.g., across vertical, horizontal, or diagonal lines) and rotational symmetry (by 120° and 240°). The shading must be identical under both reflections and rotations.
Parent Tip: Review the logic above to help your child master the concept of printable shapes for rotational symmetry.
