What are Parallel and Perpendicular Lines? Definition, Examples
perpendicular Lines that are perpendicular intersect to form a 90∘ 90 ∘ angle The slope of one line is the negative reciprocal of the other We can show that two lines are
Perpendicular Lines Theorem If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular line Proof: perpendicular Setting out Perpendicular Lines: the Rope Method A line has to be set out perpendicular to the base line from peg Peg is not on the base line A
