Choose the correct answers from the given four option:

Let F1 be the set of parallelograms, F2 the set of rectangles, F3 the set of rhombuses, F4 the set of squares and F5 the set of trapeziums in a plane. Then F1 may be equal to,

  1. \(\text{F}_2\cap\text{F}_3\)

  2. \(\text{F}_2\cup\text{F}_3\cup\text{F}_4\cup\text{F}_1\)

  3. \(\text{F}_2\cup\text{F}_5\)

  4. \(\text{F}_3\cap\text{F}_4\)

Solution

Solution:

Every rectangel, rhombus, square in a plane is a parallelogram but every trapezium is not a parallelogram.

\(\text{F}_1=\text{F}_2\cup\text{F}_3\cup\text{F}_4\cup\text{F}_1\)
