Identify the figure that has a line of symmetry.

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

Solution:

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

Among the figures, 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.

Identify the letter that has the dotted line dividing it into two symmetrical halves.

 a. V b. X c. A d. all three letters

Solution:

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

The lines passing through the letters A, V, and X divide them into two parts that would be the mirror images of each other.

So, the dotted lines for all the three alphabets are the lines of symmetry.

Is the dotted line through the wall hanging a line of symmetry?

 a. No b. Yes

Solution:

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

The dotted line through the wall hanging divides the wall hanging into two parts, which are mirror images of each other.

So, the dotted line through the wall hanging is a line of symmetry.
