Question

introduction to proof a two - column proof uses inductive reasoning to prove a statement. contains a table with a logical series of statements and reasons that reach a conclusion. contains a set of sentences explaining the steps needed to reach a conclusion. uses a visual representation of the logical flow of steps needed to reach a conclusion.

Explanation:

To determine the correct description of a two - column proof:

1. Recall the definition of a two - column proof: A two - column proof is a type of proof in geometry (and other areas of mathematics) that is organized in a table. One column contains a series of statements, and the other column contains the corresponding reasons (justifications) for those statements, and together they are used to reach a conclusion.
2. Analyze the given options:

• The option "uses inductive reasoning to prove a statement" is incorrect. Two - column proofs typically use deductive reasoning, where we start from given information and use logical rules and previously proven theorems to reach a conclusion. Inductive reasoning is based on patterns and is not the basis of a two - column proof.
• The option "contains a table with a logical series of statements and reasons that reach a conclusion" matches the definition of a two - column proof.
• The option "contains a set of sentences explaining the steps needed to reach a conclusion" is more like a paragraph - style proof (or a narrative proof) rather than a two - column proof.
• The option "uses a visual representation of the logical flow of steps needed to reach a conclusion" describes a flow - chart proof, not a two - column proof.

So the correct option is the one that says "contains a table with a logical series of statements and reasons that reach a conclusion".
