Argue This! ... Syllogism?

Syllogism >
Preston : Is the simplest form of a logical argument.
Ex. : All lines have 180 degrees, an object has a 180 degree, therefore this is a line.
There’s the truth, thats it.
True : is factually, when it comes to logic there’s no faith.

Does the premises support the conclusion?
Ex. : All students at SMHS are all nice people.
Lilly is a student at SMHS so that means she is nice.
If its not factually valid, then it’s not true.

Deductive reasoning : General idea to specific example, case or conclusion
Ex. : Sherlock Holmes 

Google : An instance of a form of reasoning in which a conclusion is drawn (whether validly or not) from two given or assumed propositions (premises), each of which shares a term with the conclusion, and shares a common or middle term not present in the conclusion (e.g., all dogs are animals; all animals have four legs; therefore all dogs have four legs ).
