Perpendicular LinesIf angle between two intersecting lines is 90° (right angle) Then they are perpendicular So, XY is perpendicular to AB ∴ XY ⊥ AB Real life examples of perpendicular lines are To make perpendicular lines, we can use a set square and a ruler Can you try making? We have taught it here - https://www.teachoo.com/8891/2839/Drawing-perpendicular-to-a-line-through-a-point---Using-ruler-and-set-/category/Perpendicular-to-a-line-through-a-point-on-it/
