Give three examples of shapes with no line of symmetry.

Hint: - Line of symmetry divides the shapes into two equal halves.
A 'line of symmetry' in a geometric shape is a line that you can draw through a shape that divides it into halves that are the same. If you folded the shape on that line, one side would overlap the other side exactly.
Therefore examples of shapes with no line of symmetry is
$\left( i \right)$A scalene triangle.
$\left( {ii} \right)$A parallelogram
$\left( {iii} \right)$A trapezium
Note: - In such types of questions the key concept we have to remember is that the line of symmetry always divides the shapes into two equal halves, and the required shapes are shown above.
