There are 5 alphabets in the word "MATHS".
'M' has line symmetry but not rotational symmetry.
'A' also has line symmetry but not rotational symmetry.
'T' also has line symmetry but not rotational symmetry.
'S' also has line symmetry but not rotational symmetry.
But the alphabet 'H' has both rotatational symmetry (of order 2) as well as line symmetry (along horizontal and vertical lines).
