Which type of statement must be proven in geometry? a. axiom
b. definition
c. postulate.
d. theorem

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.
