They can then recognize the similarities and differences between them. Question 2: Define the working of the Venn diagrams.Īnswer: Venn diagrams permit the students to arrange the information visually so that they are able to see the relations between 2 or 3 sets of the items. Then represent A – B and B – A through Venn diagrams. we have operations on Venn diagrams that are given as follows: Union of Sets Just like the mathematical operations on sets like Union, Difference, Intersection, Complement, etc. The elements are written within the circle representing the set containing them and the common elements are written in the parts of circles that are overlapped.Sets having no element in common are represented separately while those having some of the elements common within them are shown with overlapping.Labelling is done for each set with the set’s name to indicate difference and the respective constituting elements of each set are written within the circles.Each individual set is represented mostly by a circle and enclosed within a quadrilateral (the quadrilateral represents the finiteness of the Venn diagram as well as the Universal set.).A Venn diagram is also known as a Primary diagram, Set diagram or Logic diagram. They are extensively used to teach Set Theory.
Venn diagrams were conceived around 1880 by John Venn, an English logician, and philosopher.
A Venn diagram is a diagrammatic representation of ALL the possible relationships between different sets of a finite number of elements.
