Question

which of the following letters does not have a line symmetry, but has a rotational symmetry?

Explanation:

Step1: Analyze line symmetry of H

If we draw a vertical line through the center of H, the left and right parts are mirror - images. So H has line symmetry.

Step2: Analyze line symmetry of i

If we draw a vertical line through the center of i (assuming a simple font where the dot is centered vertically), the left and right parts (excluding the dot, but considering the main vertical stroke) are mirror - images. So i has line symmetry.

Step3: Analyze line symmetry of Z

If we try to draw a line (vertical, horizontal, or diagonal) to make Z have line symmetry, we can't find such a line. But if we rotate Z by 180 degrees around its center, it looks the same. So Z has rotational symmetry but no line symmetry.

Answer:

Z
