Het raster vertoont horizontale, verticale of puntsymmetrie.

Symmetry patterns require the grid to mirror itself along an axis or around a central point. Horizontal symmetry means left and right columns are reflections. Vertical symmetry means top and bottom rows mirror each other. Point symmetry (180° rotational) means opposite corners match.

Horizontal: cell[r][0] = cell[r][2], Vertical: cell[0][c] = cell[2][c], Point: cell[r][c] = cell[2-r][2-c]

• Left column shapes identical to right column shapes
• Top row mirrored in bottom row
• Corners with matching shapes (top-left = bottom-right)

Zo herkent u het

• Compare opposite sides of the grid
• Check if folding the grid would align shapes
• Look for matching pairs across the center

Veelgemaakte fouten

• Confusing horizontal and vertical symmetry
• Not checking all symmetric pairs
• Missing point symmetry around the center
