Write and apply proofs about parallel and perpendicular lines. Lines that do not intersect are parallel lines. 2. Prove theorems about perpendicular lines. are parallel, then find a. We know that if we have two lines that are parallel-- so let me draw those two parallel lines, l and m. So that's line l and line m. We know that if they are parallel, then if we were to draw a transversal that intersects both of them, that the corresponding angles are equal. Angle bisectors. Slopes of parallel and perpendicular lines 6. Lines that do not intersect are parallel lines. Fill in the blanks for the following two-column proof. 2.4 Perpendicular Line and Perpendicular Bisector.
