Here are the matched pairs:
axiom: statement that is assumed to be true without proof
common notion: Statement that is understood to be common sense
definition: statement that describes the qualities of an object or process
proof: method for showing that a mathematical idea or conjecture is true
theorem: statement that has already been proven to be true
Axiom: An axiom is a statement that is accepted as true without requiring proof. It serves as a basic assumption or starting point for further reasoning.
Common Notion: Common notions are statements that are understood to be self-evident or common sense. They are basic principles that are widely accepted and do not require elaborate proof.
Definition: A definition is a statement that describes the qualities or essential characteristics of an object or process. It provides clarity and understanding of a particular concept.
Proof: Proof is a method or process used to demonstrate that a mathematical idea or conjecture is true. It involves logical reasoning and a series of steps to establish the validity of a statement.
Theorem: A theorem is a statement that has been proven to be true based on accepted axioms, definitions, and previously proven theorems. It is a result derived through logical deduction.
