Perpendicular lines are intersecting lines. Parallel and Perpendicular Lines Worksheet Answers. Equations of lines 5. Practice. Problem 4 : In the diagram given below, the lines m and n are perpendicular. Justify your conclusion. 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. Equations of parallel and perpendicular lines 7.
