Perpendicular Lines Intersect To Form Right Angles - This is why the corners of a square always form right angles. Web they are considered to be perpendicular lines because they form a right angle at their point of intersection. For example, perpendicular lines are seen in many common 2d shapes. Web perpendicular lines are lines that intersect to form 90^{\circ} angles (right angles). For example, each side of a square is perpendicular to the adjacent sides (the sides that touch).
