Law of noncontradiction
In logic, the law of non-contradiction( LNC)( also known as the law of contradiction, principle of non-contradiction( PNC), or the principle of contradiction) states that contradictory propositions can not both be true in the same sense at the same time, e. g. the two propositions A is B and A is not B are mutually exclusive.
Formally this is expressed as the tautology ¬( p ∧ ¬p).
One reason to have this law is the principle of explosion, which states that anything follows from a contradiction.
The law is employed in a reductio ad absurdum proof.
To express the fact that the law is tenseless and to avoid equivocation, sometimes the law is amended to say" contradictory propositions can not both be true' at the same time and in the same sense'".
It is one of the so called three laws of thought, along with its complement, the law of excluded middle, and the law of identity.
The law of noncontradiction is logically equivalent to the law of excluded middle by De Morgan's laws.
However, no system of logic is built on just these laws, and none of these laws provide inference rules, such as modus ponens or De Morgan's laws.
The law of non contradiction and the law of excluded middle create a dichotomy in" logical space", wherein the two parts are" mutually exclusive" and" jointly exhaustive".
The law of non-contradiction is merely an expression of the mutually exclusive aspect of that dichotomy, and the law of excluded middle, an expression of its jointly exhaustive aspect.

Law of tangents

In Figure 1,,, and are the lengths of the three sides of the triangle, and,, and are the angles" opposite" those three respective sides.
The law of tangents states that The law of tangents, although not as commonly known as the law of sines or the law of cosines, is equivalent to the law of sines, and can be used in any case where two sides and the included angle, or two angles and a side, are known.
