Which of the following is not a symmetrical figure
Solution:
A shape or an object has symmetry if it can be divided into two identical pieces.
In a symmetrical shape, one-half is the mirror image of the other half.
The imaginary axis or line along which the figure can be folded to obtain the symmetrical halves is called the line of symmetry.
From the options given
We find the option d is not a symmetrical figure
Therefore, option d is not a symmetrical figure.
✦ Try This: Give examples of shapes which has no line of symmetry.
The line of symmetry is a line that divides an object into two identical pieces.
When a figure is folded in half, along its line of symmetry, both the halves match each other exactly.
This line of symmetry is called the axis of symmetry.
A scalene triangle, parallelogram and a trapezium does not have any line of symmetry as shown below as no line divides these shapes into two identical shapes.
Therefore, a scalene triangle, parallelogram and a trapezium are the examples
