เว็บไซต์ perpendicular 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 perpendicular Parallel lines never intersect each other They are non-intersecting lines Perpendicular lines are two intersecting lines They intersect each other at right
perpendicular As shown in Figure 3, if two lines are both perpendicular to a third line , all of the angles formed on the third line are right angles Therefore, A perpendicular is a straight line that makes an angle of 90° with another line 90° is also called a right angle and is marked by a little square between two Two lines are perpendicular when they intersect to form a 90 ∘ angle Below, l ⊥ A B ¯
