If you are able to fold a figure along a line so that the folded part lines up with the unfolded part, then we have found a line of symmetry. We can fold a word in two ways that could be potential lines of symmetry. Either we fold the top half over the bottom half, or we fold the left half over the right half.

If we fold the top half over the bottom half, the letter L will not fold symmetrically. Moreover, since L and K are different letters, folding the left half over the right half does not create a perfect match. We can conclude that there is **no** line of symmetry for the word LOOK

b

Let's illustrate the two ways we can fold the word MOM

.

If we fold the top half over the bottom half, neither M will fold symmetrically. Therefore, this can't be a line of symmetry. Conversely, folding the left half over the right half, the O will fold in half and one M will line up with the other M. Thus, we can conclude that there is $1$ line of symmetry for the word MOM

c

Let's illustrate the two ways we can fold the word OX

.

If we fold the top half over the bottom half, both letters O and X will fold over themselves. Therefore, this is a line of symmetry. Conversely, since O and X are different letters they won't line up if we fold the left half over the right half. Thus, we can conclude that there is $1$ line of symmetry for the word OX

.

d

Let's illustrate the two ways we can fold the word DAD

.

If we fold the top half over the bottom half, the letter A will not fold in half. Folding the left half over the right half, the Ds will not line up. Remember that a line of symmetry creates a mirror image. Thus, we can conclude that there are **no** lines of symmetry for the word DAD
