Perpendicular lines are lines that intersect at right angles By using Pythagoras's Theorem it can be shown that two lines with slopes m1 and m2
Two lines that intersect and form right angles are called perpendicular lines The symbol ⊥ is used to denote perpendicular lines In Figure , line l ⊥ line m To play this video you need to enable JavaScript in your browser Parallel lines are always the same distance apart for their entire length Perpendicular lines
เซเรียบี อิตาลี Multiplying the slopes of nearly any two perpendicular lines will give you a product of -1, meaning that they are opposite reciprocals of each other The lone Perpendicular Lines Theorem If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular line Proof:
