Question
Given, $A = \{$Triangles$\}, B = \{$Isosceles triangles$\}, C = \{$Equilateral triangles$\}$. State the following statement is true or false. Give reasons.$A ⊂ B$
✓

Answer

False.
Reason:
$A = \{$Triangles$\}$
$B = \{$Isosceles triangles$\}$
$C = \{$Eqilateral triangles$\}$
Since each triangle is not isosceles.
$\therefore A ⊂ B$
Hence,$ A ⊂ B$ is false.
