1.	Let F1 be the set of all parallelograms, F2 the set of all rectangles, F3 the set of all rhombuses, F4 the set of all squares and F5 the set of trapeziums in a plane. Then F1 may be equal to(a) F2∩F3 (b) F3∩F4 (c) F2∪F3 (d) F2∪F3∪F4∪F1
Answer» Let F₁ be the set of all parallelograms, F₂the set of all rectangles, F₃the set of all rhombuses, F₄the set of all squares and F₅the set of trapeziums in a plane. Then F₁ may be equal to (a) $F_{2} \cap F_{3}$ (b) $F_{3} \cap F_{4}$ (c) $F_{2} \cup F_{3}$ (d) $F_{2} \cup F_{3} \cup F_{4} \cup F_{1}$
