Worked Solution
Step 1: Draw the letter E and test the horizontal axis (fold top half onto bottom half). The top arm maps exactly onto the bottom arm, and the middle arm lies on the fold line. The two halves match — this IS a line of symmetry.
Step 2: Test the vertical axis (fold left half onto right half). The three arms are on the left side; the right side is blank. The halves do NOT match — this is NOT a line of symmetry.
Step 3: No other axes (diagonal, etc.) produce matching halves.
Answer: The letter E has 1 line of symmetry (horizontal).
Answer: 1
