Linear+Pair+Postulate,+1

=Linear Pair Postulate = Period 1 Erin Sheehy Elena Spaulding Cricket Martin

Problems:
 * 1) if ∠1 & ∠2 are a linear pair then m∠1 + m∠2 = 180. (example from 2.7 worksheet)
 * 2) Given: ∠1 & ∠2 are supplementary Prove: ∠ 3 ≅ ∠2 (proof from 2.7 worksheet)

Answers: 1. linear pair postulate

2. Given; definition of linear pair; linear pair postulate; definition of supplementary angles; segments congruence theorem

This is an example of a Linear Pair Postulate



Statement Reason

m∠1 + m∠2 = 180 Linear Pair Postulate
