select one or more:
a. formulas
b. postulates
c. definitions
d. theorems
e. properties

Explanation:

Identify valid reasons in a geometric proof

$$ \text{Valid reasons} = \{\text{Postulates}, \text{Definitions}, \text{Theorems}, \text{Properties}\} $$

Evaluate the role of formulas

$$ \text{Formulas} otin \text{Standard Proof Reasons (unless expressed as a theorem/property)} $$

Answer:

• a. Formulas
• b. Postulates (Correct answer)
• c. Definitions (Correct answer)
• d. Theorems (Correct answer)
• e. Properties (Correct answer)
