Mark the correct alternative in the following: Let F 4 be the set of all parallelograms, F 2 the set of all rectangles, F 3 the set of all rhombuses, F 4 the set of all squares and F 5 the set of trapeziums in a plane. Then F 1 may be equal to

Question

Philoid · Accepted Answer

Here, F₁ is the set of all parallelograms

We know that every rectangle, rhombus and square in plane are parallelogram but trapezium is not parallelogram

So, .
