Write all capital letters of the English Alphabet which have two lines of symmetry
[a] H, I and X
[b] A, C and B
[c] P, Q and R
[d] S, Y and Z

Hint: List all the capital letters of the English Alphabet and find the number of lines of symmetry of each. The letters which have two lines of symmetry will be accepted, while those have less than two or more than two will be rejected.

Complete step-by-step answer:

Line of symmetry is a line about which the two halves of the object are mirror images of each other.
A: “A” has only one line of symmetry as shown below


B: “B” has one line of symmetry

C: “C” has one line of symmetry


D : D has one line of symmetry


Similarly, we can show that
E has one line of symmetry
F has zero lines of symmetry
G has zero lines of symmetry
H has two lines of symmetry
I has two of symmetry
J has zero lines of symmetry
K has one line of symmetry
L has zero lines of symmetry
M has one line of symmetry
N has zero lines of symmetry
O has infinite lines of symmetry
P has zero lines of symmetry
Q has zero lines of symmetry
R has zero lines of symmetry
S has zero lines of symmetry
T has one line of symmetry
U has one line of symmetry
V has one line of symmetry
W has one line of symmetry
X has two lines of symmetry
Y has one line of symmetry
Z has zero lines of symmetry
Hence H, I and X have two lines of symmetry.
Hence option [a] is correct.

Note: The lines of symmetry in H, I and X are shown below
