True
Postulate, Corollary, Definition, & Theorem
Yo could try using logic.
Corollary.Theorem.Definition.Postulate.
that is a thereom
Axioms, definitions, and theorms that have been proven.
Proven Theorems.. Plato ;)
Neither true nor false. Some theorems can be proven using geometric arguments and methods, others cannot.
Yes. That is what theorems are for. Once proven, their results do not need to be justified again (except for exams).
postulates
Steps in a geometric proof do not require support
There is no single statement that describes a geometric proof.
Both the algebraic proof and geometric proof are strong. The algebraic proof however is usually very involving.
Axioms and logic (and previously proved theorems).
The adjective for "proof" would be "proven."
A proof that uses techniques from geometry.
