Concept:In geometry, writing proofs means logically justifying each statement using definitions, axioms, and previously proved results.
Explanation:Mathematics is a deductive system. It begins with undefined terms and self-evident truths called axioms.
From these axioms, we define new objects and prove theorems step by step.
A proof is not just drawing a figure or listing axioms in a table. It is a clear chain of reasoning.
Each step in a proof must be supported by a definition, an axiom, or a previous theorem.
Thus, writing proofs is about giving a logical argument or justification for the statements made.
Answer:Option C: argument or justification of statements
