Okay, now I see the bottom-right pattern. The mirror line is vertical. On the right side, there's a red shape that looks like a 'T' with an extra square on the bottom right. Specifically, there are red squares in row 1, columns 5 and 7; row 2, column 6; row 3, column 6; and row 4, columns 5 and 7. To complete this symmetrically, I need to reflect each of these squares across the vertical mirror line onto the left side. For instance, the square at (row 1, col 5) will be mirrored to (row 1, col 3), and the square at (row 4, col 7) will be mirrored to (row 4, col 1). I have now examined all eight patterns.
I will now synthesize the solution for all patterns.
The task is to complete the other half of each pattern by reflecting it across the given "Mirror line". Since the mirror lines are all vertical, we must create a mirror image of the existing red squares on the opposite side of the line.
Here is the completed solution for each pattern:
Top-Left Pattern:
The left side has a 'T' shape with an extra square. The right side should be its exact mirror image.
- Row 1: Red squares in columns 5, 6, 7.
- Row 2: Red square in column 6.
- Row 3: Red squares in columns 6, 7.
- Row 4: Red squares in columns 6, 7.
Top-Right Pattern:
The left side has an 'L' shape with an extra square. The right side should be its exact mirror image.
- Row 2: Red square in column 5.
- Row 3: Red squares in columns 4, 5, 6.
Middle-Left Pattern:
The left side has a 'T' rotated 90 degrees to the right. The right side should be its exact mirror image.
- Row 1: Red square in column 5.
- Row 2: Red square in column 5.
- Row 3: Red square in column 5.
- Row 4: Red square in column 6.
Middle-Right Pattern:
The left side has a 'T' with an extra square on the bottom right. The right side should be its exact mirror image.
- Row 1: Red squares in columns 2, 4.
- Row 2: Red square in column 3.
- Row 3: Red square in column 3.
- Row 4: Red squares in columns 2, 4.
Bottom-Left Pattern:
The right side has a 'T' with an extra square on the bottom right. The left side should be its exact mirror image.
- Row 1: Red squares in columns 3, 5.
- Row 2: Red square in column 4.
- Row 3: Red square in column 4.
- Row 4: Red squares in columns 3, 5.
Bottom-Right Pattern:
The right side has a 'T' with an extra square on the bottom right. The left side should be its exact mirror image.
- Row 1: Red squares in columns 3, 5.
- Row 2: Red square in column 4.
- Row 3: Red square in column 4.
- Row 4: Red squares in columns 3, 5.
By following these steps, each pattern is completed to be symmetrical across the vertical mirror line.
