(b) Correct answer: 2 Marks


(a)



(b) Line symmetry, mirror symmetry and reflection symmetry are nearly same.

If you fold the figure along the line representing the water level, then the lower half will perfectly align with the upper half. This means the water level is the line of symmetry. This happens because of reflection. The upper and lower halves cannot be different.

At conceptual level, there is no difference between line symmetry and mirror/reflection symmetry
