Question

Some english alphabets have fascinating symmetrical structures. From the following table, find the number of alphabets which have both the lines symmetry and rotational symmetry more than 1

Alphabets	Line symmetry	Number of lines symmetry	Rotational symmetry	Order of rotational symmetry
$Z$	No	$0$	Yes	$2$
$S$	No	$0$	Yes	$2$
$H$	Yes	$2$	Yes	$2$
$O$	Yes	$2$	Yes	$2$
$I$	Yes	$2$	Yes	$2$
$N$	No	$0$	Yes	$2$
$C$	Yes	$1$	No	$1$

Answer 1

From the table, we can clearly see that $H,O$ and $I$ have both the lines symmetry and rotational symmetry as $2$.
