Question

3. Let U = {set of all quadrilaterals), A = (set of all parallelograms), B = (set of all rectangles) and C = {set of all rhombuses}. Represent this by means of a Venn diagram. What will be the type of quadrilateral which belongs to B ununiversal C?​

Answer 1

Answer:

a. Let U→ Set of closed geometrical figures.

C→ Set of all polygons

P→ Set of all circle.

⇒ The above Fig (a) Venn diagram represents the truth of given statements i.e.,C∩P=ϕ

b. Let U→ The set of all quadrilateral

P→ The set of all parallelogram

Q→ The set of all rhombus.

⇒ The above fig (b) Venn diagram represents the truth of given statement i.e. Q⊂P
