Which letter in the word HAPPY has an order of 2 rotational symmetry?

Solution:

Rotational symmetry is the symmetry wherein the figure looks exactly the same if you rotate it about any fixed point.

A figure is symmetrical if it can be divided into two identical pieces.

If you turn or rotate a figure about a point H, if it will still look the same from all directions, this kind of symmetry is called rotational symmetry.

The order of rotational symmetry of the letter H is 2.

So, H has the order of 2 rotational symmetry.
