What is the purpose of marking up the diagram when doing proofs?

• To make the proof longer

• To confuse the reader

• To make the diagram look colorful

• To avoid remembering all details while doing the proof

What does the segment addition postulate state?

• Two segments added together equal the whole segment

• Two segments subtracted equal the whole segment

• Two segments multiplied equal the whole segment

• Two segments divided equal the whole segment

Why is it important to state that segment XY is equal to itself?

• Because it is not obvious

• To use it in the subtraction property of equality

• To make the proof longer

• To confuse the reader
