Most animals also exhibit mirror symmetry. Some examples of such animals are shown below.
Symmetry in Buildings and Monuments
Most buildings and monuments exhibit symmetry. Look at
Top Tip
the pictures of the monuments shown below.
Taj Mahal is famous for its
symmetry as well as geometric
patterns. The monument is
identical on either side of the
plane of symmetry. It also shows
symmetry along the water line
showing reflection in
the water.
In these structures, the plane of symmetry divides the structure into two equal halves where the
left and right halves are the mirror images of each other.
Exercise 9.3
1. Draw the plane(s) of symmetry for the following figures, if any.
(a) (b) (c) (d)
2. Select the figures that are symmetrical about the plane drawn.
(a) (b) (c)
(d) (e) (f)
