WHAT HAVE WE DISCUSSED?
A figure is said to have line symmetry if a line can be drawn dividing the time
identical parts. This line is called a line of symmetry
A figure may have no line of symmetry, only one line of symmetry two lines of
multiple lines of symmetry. Here are some examples
Number of lines of symmetry
No line of symmetry
Only one line of symmetry
Two lines of syrnmetry
Three lines of symmetry
Countless lines of symmetry
Example
A scalene triangle
An isosceles triangle
A rectangle
An equilateral triangle
A circle
3.
The line symmetry is closely related to mirror reflection. When dealing with minor reflection
we have to take into account the left right changes in onentation
Symmetry has plenty of applications in everyday life as in art, architecture, textile technology
design creations, geometrical reasoning, Kolams, Rangoli etc.
