Geometry 2.5 Proofs Quiz

Why does the order of the statements and reasons in a proof matter?

• To show logical progression

• To make the proof longer

• To confuse the reader

• To add unnecessary information

• A proof with two columns of text

• A proof with two sets of reasons

What is deductive reasoning?

• Reasoning based on guesswork

• Reasoning based on facts and logic
