line perpendicular to a plane
This is a picture of a ceiling and a wall meeting. This is something people see almost every day. It will be in most rooms. It represents a line perpendicular to a plane. The ceiling is the plane and the wall shows the perpendicular line. When the wall meets the ceiling a 90 degree angle is formed. It is important to have that 90 degree angle or else the ceiling will be off balance. This is a picture that I took myself, it is not from the internet.
