Question

. Let F1 be the set of parallelograms , F2 be the set of rectangles,
Fz be the set of rhombus and F4 be the set of squares. Then
show that Fi is equal to union of all sets.​

Answer 1

since we know the properties of a parallelogram

it's opp sides are equal and parallelel

in F2 rectangles has opposite sides equal and parallel

Fz rhombus which has all sides equal and parallel

F4 squares show also the same properties

but square is different from rhombus and rectangle and vice versa therefore F2 Fz and F4 can't be universal sets

hence F1 is universal set
