MIRROR SYMMETRY
Definition Of Mirror Symmetry
Mirror Symmetry occurs when two halves of object is the mirror images of each other.
More About Mirror Symmetry
Mirror symmetry is also called as bilateral symmetry
Examples of Mirror Symmetry
23, 46, 19, 5, 12, 29, 8, 42
The left half of the butterfly and its mirror image also depict the whole butterfly; therefore the butterfly has mirror symmetry.

Solved Example on Mirror Symmetry
Ques: Choose the figures that show the mirror symmetry for the given figure.
Choices:
A. Figure 1
B. Both Figure 1 and Figure 2
C. Figure 2
D. None of the above
Correct Answer: C
Solution:
Step 1: A figure is symmetric about a mirror if one side of the figure is mirror image of its other side of the figure.
Step 2: The mirror shown in Figure 2 divides the figure into two equal halves such that each half is the mirror image of the other.
Step 3: So, Figure 2 shows the mirror symmetry for the given figure.
Quick Summary
- Mirror symmetry means one half of an object is a reflection of the other.
- It's also called bilateral symmetry.
