Think about the parts of the proof logically and determine step-by-step how to get from the givens to the final conclusion. Notice that when the SAS postulate was used, the numbers in parentheses correspond to the numbers of the statements in which each side and angle was shown to be congruent. You won't have to put up with that forever.

LA is a right angle. Given: Segment AD bisects segment. If you're trying to prove that base angles are congruent, you won't be able to use "Base angles are congruent" as a reason anywhere in your proof. Q: nswer these statements: True or False? Anytime it is helpful to refer to certain parts of a proof, you can include the numbers of the appropriate statements in parentheses after the reason.

Q: Which postulate proves these two triangles are congruent? Try to order all of your steps so that they naturally follow each other. This can be frustrating; however, there is an overall pattern to solving geometric proofs and there are specific guidelines for proving that triangles are congruent.
