Question 9 • Geometry: Concepts and Connections

Which are correct statements regarding proofs? Choose three correct answers.

Answer
A
A two-column proof consists of a list statements and the reasons the statements are true.
B
A flowchart proof is a visual way of describing the statements and reasons for a proof.
C
In a paragraph proof, statements and their justifications are written in sentences in a logical order.
D
A two-column proof lists only the given information and what is to be proven.
E
A flowchart proof gives a visual representation of the sequence of steps without justifications.

Explanation

A flowchart proof uses a visual layout to show the statements and the reasons supporting them, so B is correct. In a paragraph proof, the statements and their justifications are written in sentences in a logical order, making C correct. A two-column proof lists statements alongside the reasons they are true, so E is correct; it includes the proof steps, not just the givens and goal as A claims.
