Worked Solution
Step 1: Understand what a line of symmetry does.
A vertical line of symmetry reflects every square on the left side to a matching position on the right side.
Step 2: Count the shaded squares on the left half.
Left half = 3 shaded squares.
Step 3: Mirror to find the right half.
Right half = 3 shaded squares (one for each on the left).
Step 4: Find the total.
3 + 3 = 6 shaded squares in the complete figure.
Correct answer: 6
