Here are the postulates and theorems that willb used in this lesson. Le E If 2a Le, CACP POSTULATE . m In, LA Given two lines cut by a transversal, if corresponding angles are 1) congruent, then the two lines are Ar 1) PC parallel. AICP POSTULATE B. mIf zd f, Given two lines a /b cut by a d * mIn. transversal, if alternate interior angles are congruent, then the lines are G Pm parallel. Pr SSIAS THEOREM Given two lines b m If zd & Le arę cut by a transversal, if same side interior a d/c supplementar : m1n. e If angles are supplementary, then the lines are parallel. The three Parallel Lines Theorem On a plane, if two lines are both a -> If n 1 and to a third pa line, then they are parallel n11, then C The Perpendicular to a Third Line Theorem If two coplanar If it and lines are i2 it, then perpendicular to a third line, then they are parallel to each other.
