Answer:
Theorem are the type of statement must be proven in geometry.
Step-by-step explanation:
1) Axiom are the statements or prepositions that are accepted and do not need any proof. Example : if a and b are real numbers then then their sum is also a real number.
2) Definition is a statement given to define something.
3) Postulates is a proposition that requires no proof and is for a specific purpose assumed true, and that is used in the proof of other propositions; axiom.
4) theorem are the statements that can be proved using axioms , definition etc.
Thus, from above all theorem are the type of statement must be proven in geometry.
