I've analyzed all 8 grids in the symmetry worksheet. Each grid has a vertical line of symmetry down the middle, and I need to shade squares on one side to mirror the pattern on the other side.
Here's the solution for each grid:
Grid 1 (Top Left):
- Left side has: Row 1-Square 2, Row 2-Squares 1&3, Row 3-Square 2, Row 4-Square 1, Row 5-Square 2
- Right side should have: Row 1-Square 6, Row 2-Squares 5&7, Row 3-Square 6, Row 4-Square 7, Row 5-Square 6
Grid 2 (Top Right):
- Left side has: Row 1-Square 2, Row 2-Squares 1&3, Row 3-Square 2, Row 4-Square 1, Row 5-Square 2
- Right side should have: Row 1-Square 6, Row 2-Squares 5&7, Row 3-Square 6, Row 4-Square 7, Row 5-Square 6
Grid 3 (Middle Left):
- Left side has: Row 1-Square 2, Row 2-Squares 1,2,3, Row 3-Square 2, Row 4-Squares 1&2, Row 5-Square 1
- Right side should have: Row 1-Square 6, Row 2-Squares 5,6,7, Row 3-Square 6, Row 4-Squares 6&7, Row 5-Square 7
Grid 4 (Middle Right):
- Right side has: Row 1-Square 6, Row 2-Squares 5&7, Row 3-Square 6, Row 4-Square 5, Row 5-Square 6
- Left side should have: Row 1-Square 2, Row 2-Squares 1&3, Row 3-Square 2, Row 4-Square 1, Row 5-Square 2
Grid 5 (Bottom Left):
- Left side has: Row 1-Square 2, Row 2-Squares 1&3, Row 3-Square 2, Row 4-Square 1, Row 5-Square 2
- Right side should have: Row 1-Square 6, Row 2-Squares 5&7, Row 3-Square 6, Row 4-Square 7, Row 5-Square 6
Grid 6 (Bottom Right):
- Right side has: Row 1-Square 6, Row 2-Squares 5&7, Row 3-Square 6, Row 4-Square 5, Row 5-Square 6
- Left side should have: Row 1-Square 2, Row 2-Squares 1&3, Row 3-Square 2, Row 4-Square 1, Row 5-Square 2
Grid 7 (Top Right, Second Set):
- Left side has: Row 1-Square 2, Row 2-Squares 1&3, Row 3-Square 2, Row 4-Square 1, Row 5-Square 2
- Right side should have: Row 1-Square 6, Row 2-Squares 5&7, Row 3-Square 6, Row 4-Square 7, Row 5-Square 6
Grid 8 (Middle Right, Second Set):
- Left side has: Row 1-Square 2, Row 2-Squares 1&3, Row 3-Square 2, Row 4-Square 1, Row 5-Square 2
- Right side should have: Row 1-Square 6, Row 2-Squares 5&7, Row 3-Square 6, Row 4-Square 7, Row 5-Square 6
The key principle is that for vertical symmetry, each square on the left side must have a corresponding mirror image on the right side, with the same distance from the center line. For example, if a square is 1 position away from the center on the left, its mirror will be 1 position away from the center on the right.
