Worksheet – Section 2-8 Proving Angle Relationships
Perpendicular lines) Perpendicular lines intersect to form four right angles. Theorem (Definition of right angles) All right angles are congruent. Theorem (Definition of Perpendicular lines) Perpendicular lines form congruent adjacent angles. Example: Write a two-column proof. Given: ∠ ABC and ∠CBD are complementary.

From behind the window, I let my finger slowly uncurl like a bean plant rising from earth. I uncurled it, then curled it back and made a fist. I should remember this day, I told myself. Name: _____

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)
