Answer: uses a visual representation of the logical flow of steps needed to reach a conclusion.
Explanation:
A two column proof uses a visual representation of the logical flow of steps needed to reach a conclusion.
It is arranged into two columns named as "statement" and "reason" columns, where each statement must have valid logical and mathematical reason needed to reach the required conclusion..
The reasons in a two column proof are generally given details, vocabulary, definitions, postulates and previously proved theorems.
Hence, the correct statement is "uses a visual representation of the logical flow of steps needed to reach a conclusion."
