If a composite proposition *p* is always true for all possible assignment of truth values to its prime components, then it is called tautology.

The following are some examples of tautology:

- (Law of excluded middle)
- (Law of contradiction)
- (Law of double negation). (The above 3 tautologies are widely known laws of classical logic.)
- (principle of syllogism)
- (law of contrapositive)

If a condition is a tautology, then we say that *p* implies *q* i.e .

**Truth table**
