Tell whether the dotted line in the figure is 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 in the figure divides the figure into two parts, which are mirror images of each other.

So, the dotted line in the figure is a line of symmetry.

72.
Is the dotted line in the figure 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 in the figure divides the figure into two parts, which are mirror images of each other.

So, the dotted line in the figure is the line of symmetry.

73.
Can one call the dotted line passing through the word 'BOB' 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 in the word divides the word into two parts, which are mirror images of each other.

So, one can call the dotted line passing through the word BOB a line of symmetry.

74.
Can one call the dotted line passing through the word 'JIM' a line of symmetry?

 a. Yes b. No

#### Solution:

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

The dotted line in the word does not divide the word into two parts, which are mirror images of each other.

So, the dotted line in the word is not a line of symmetry.

75.
Does the dotted line appear to be a line of symmetry?

 a. Yes b. No

#### Solution:

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

The dotted line in the figure divides the figure into two parts, which are mirror images of each other.

So, the dotted line in the figure appears to be a line of symmetry.

76.
Which of the following letters have both vertical and horizontal lines of symmetry?
 a. J b. V c. G d. H

#### Solution:

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

In the choices, the letter H has both a vertical and a horizontal line of symmetry as follows.

The letters G, J, and V do not have both vertical and horizontal lines of symmetry.

77.
Which figure doesn't show a line of symmetry?

 a. Figure 2 b. Figure 1 c. Figure 3 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, the dotted line through the letter Q does not divide it into two parts which are mirror images of each other.

The lines passing through the letters H, M, and O divide them into two parts that would be mirror images of each other.

78.
Which figure does not show a line of symmetry?

 a. Figure 1 b. Figure 2 c. Figure 3 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, the dotted line through the letter J does not divide it into two parts which are mirror images of each other.

The lines passing through the letters B, C, and E divide them into two parts that would be mirror images of each other.

79.
Which of the dotted lines is a line of symmetry?

 a. Figure 1 b. Figure 2 c. Figure 3 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, the dotted line through the letter H divides it into two parts, which are mirror images of each other.

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

80.
Which of the following tiles best replaces the question mark for the quilt block to be symmetrical?

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

#### Solution:

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

The tile in the quilt should replace the question mark in order that the quilt be symmetrical.

So, Figure 2 should replace the question mark for the quilt block to be symmetrical.
