Step 1: Check each letter for lines of symmetry H: Has a horizontal line through the middle (top and bottom halves match) T: Has a vertical line through the stem (left and right halves match) X: Has vertical, horizontal, and diagonal lines of symmetry L: No line of symmetry. If folded vertically, the parts don't match. If folded horizontally, they don't match either. Answer: L does NOT have a line of symmetry.
