The term corollary it can be used in various contexts. On the one hand it serves us and is widely used for speak or give an account of the consequence of some question. For example and in this sense, the term in question, in the context of a journalistic chronicle that refers to the war action that is taking place in a particular region of planet earth, serves to give the reader an idea of why such action occurred. Finally. To be more graphic, in that review, surely, the journalist uses the term corollary to want to give an idea of later, that is, after an incessant amount of violent events and confrontations, the corollary or the final result of these was the aforementioned war action that took place.
And on the other hand, in a mathematical context for example, A corollary is a proposition that does not need to be proven, but is very easily deduced from what was previously shown. It is generally a statement that immediately follows a theorem.
A concrete example is the best way to understand this second reference to the term. From the theorem that states that the sum of the measures of the interior angles associated with a triangle is 180 °, it follows as corollary number one that the sum of its acute angles is 90 ° and as a second corollary it follows that a triangle cannot have more than one right angle or more than one obtuse angle.
