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

#### Solution:

Line of symmetry is a line that divides the figure into two parts which are mirror images of each other.

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.

Identify the figure for which a line of symmetry can be drawn.

 a. Figure 2 b. Figure 3 c. Figure 1 d. Figure 4

#### Solution:

Line of symmetry is a line that divides the figure into two parts, which are mirror images of each other.

Among the choices, a vertical line drawn through Figure 3, divides it into two parts, which are mirror images of each other.

So, one can draw a line of symmetry for Figure 3.
