21.

Which of the dotted lines is a line of symmetry?

a. | the dotted lines in Figure 1 | ||

b. | the dotted lines in Figure 3 | ||

c. | the dotted lines in Figure 2 | ||

d. | the dotted lines in Figure 4 |

Among the choices, the dotted line through the letter Y divides it into two parts which are mirror images of each other.

The lines passing through the letters A, U, and V do not divide them into two parts that would be mirror images of each other.

So, the dotted line passing through the letter Y is a line of symmetry.
