### Grade 8 - Mathematics4.38 Set, Subset and Super set

 1. A set "A" is a subset of B, if and only if every element of A is also an element of B, and is denoted by A Ģ B. Example: A = {a,e,i,o,u}, B = {a,b,c,d,e,f,g,h,...........,z} All the elements in the set A are in set B. a Ī A and a Ī B e Ī A and e Ī B i Ī A and i Ī B o Ī A and o Ī B u Ī A and u Ī B \ A Ģ B [Read as A subset of B] The above statement is also expressed as B contains A this is written as B É A and read as B is super set of A. 2. Every set is a subset of itself. Example: A = {1,2,3}, B = {1,2,3} Every element of A is also an element of B. \ A Ģ B ---------(I) Similarly every element of B is also in A. \ B Ģ A ---------(II) From the above tow statements A = B \ Every set is a subset of itself. 3. Y Ģ X and Y¹ X, then Y is called the proper subset of X. Example: X = {1,2,3,4}, Y = {3,4} From above two sets every element of Y is also an element of X. \ Y Ģ X And we observe that the two sets are not equal i.e.Y¹ X. 4. A is not a subset of B if A contains at least one element which is not in B. A Ė B or B Ė A. 5. The empty set is a subset of every set. Directions: Check the given statements true or false. Also write at least ten examples of your own.
 Q 1: If A = {1,2,3,4} ; B = {2,4} ; C = {1,2,3,4,7} ; Ę = {} ; Q = {a,e,i,o,u} Then A Ė Q is _______.FalseTrue Q 2: If A = {1,2,3,4} ; B = {2,4} ; C = {1,2,3,4,7} ; Ę = {} ; Q = {a,e,i,o,u} Then Ę Ė A is _______.FalseTrue Q 3: If A = {1,2,3,4} ; B = {2,4} ; C = {1,2,3,4,7} ; Ę = {} ; Q = {a,e,i,o,u} Then {e} Ģ Q is ______.TrueFalse Q 4: If A = {1,2,3,4} ; B = {2,4} ; C = {1,2,3,4,7} ; Ę = {} ; Q = {a,e,i,o,u} Then A Ė B is ______.FalseTrue Question 5: This question is available to subscribers only!
