Hiii..!! Here is ur answer
Tautology = A tautology is a statement that is always true, no matter what. If you construct a truth table for a statement and all of the values of statements are true (T) then, statement is tautology because It's always true.
If you are given a statement and you want to determine if it is a tautology, then all you need to do is construct a truth table for the statement and look at the truth values in the final column, if all values are (T) means true then statement is tautology.
Hope this will help u..
