Step 1: Test the vertical line of symmetry. Draw a vertical line through the centre of H, splitting it into a left half and a right half. The left upright and right upright are mirror images → this IS a line of symmetry. Step 2: Test the horizontal line of symmetry. Draw a horizontal line through the midpoint of the crossbar of H, splitting it into a top half and a bottom half. The top half and bottom half are mirror images → this IS a line of symmetry. Step 3: Test diagonal lines. A diagonal fold of H does not produce two matching halves → NOT a line of symmetry. Step 4: Count. Lines of symmetry = 2 (one vertical, one horizontal). Answer: 2
