Question

Given, $A=\{$Quadrilaterals$\}$, $B=\{$Rectangles$\}$, $C=\{$Squares$\}$, $D=\{$Rhombuses$\}$. State whether the following statement are correct or incorrect. Give reasons.

$B$ $\subset$ $C$.

Answer 1

$A=\{$Quadrilateral$\}$

$B=\{$Rectangle$\}$

$C=\{$Squares$\}$

$D=\{$Rhombuses$\}$

$B$ is not a proper subset of $C$ as all rectangles are not squares.
So $B\subset ̸C$.
