Theorem (Definition of Perpendicular lines) Perpendicular lines form congruent adjacent angles. Example: Write a two-column proof. Given: ∠ ABC and ∠CBD are complementary.

Given: a b a b m,, Prove: m PROOF: a ll b and a l means that l b since a line perpendicular to parallel lines is perpendicular to both lines (thm 3-9). Since l b and we are given b m, then l ll m since two lines perpendicular to the same line must be parallel to each other (thm 3-8)

www.mathplane.comProofs and Postulates: Triangles and Angles Parallel Line Postulate: If 2 parallel lines are cut by a transversal, then their coresponding angles are congruent. A simple sketch can show the parallel line postulate. note: moving each point the same distance and direction will produce a parallel line (and a coresponding angle)
