Question

If $A=\left\{Parallelograms\right\}$ $B=\{Square,Rectangle,Rhombus,Trapezium\}$Then find $B-A$.

Answer 1

It is given that,

If $A=\left\{Parallelograms\right\}$

$B=\{Square,Rectangle,Rhombus,Trapezium\}$

In all parallelograms opposite sides are equal, opposite sides are parallel and opposite angles are equal

In $B$ there are four geometric figures,

$\Rightarrow$ Square - square is a parallelogram

$\Rightarrow$ Rectangle - is a parallelogram

$\Rightarrow$ Rhombus - is a parallelogram

$\Rightarrow$ Trapezium - is not a parallelogram because opposite sides are not equal and parallel.

$\therefore$ $B-A=\left\{Trapezium\right\}$
