 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


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.
