Let F(1) be the set of parallelograms, ...

Let `F_(1)` be the set of parallelograms, `F_(2)` the set of rectangle , `F_(3)` the set of rhombuses, `F_(4)` the set of squares and `F_(5)` the set of trapeziums in a plane. Then, `F_(1)` may be equal to

A

`F_(2) cap F_(3)`

B

`F_(3) cap F_(4)`

C

`F_(2) cup F_(5)`

D

`F_(2)cup F_(3) cup F_(4) cup F_(1)`

Text Solution

Verified by Experts

The correct Answer is:
D
Every rectangle ,rectangle , rhombus ,square in a place is a parellelograme but every trapezium is not a pareallelogram
`therefore F_(1)=F_(2) cup F_(3)F_(4) cup F_(1)`
