A line perpendicular to a plane

This is a image of a smart board. It is also a example of a line perpendicular to a plane. As seen in this picture, the pen held against the plane, demonstrates a line coming directly out of the smart board, forming a perpendicular line. This smart board was found in Ms. Palmer's room in Creeden Hall and was taken off my phone. Smart boards are often used to take notes, solve problems, and teach lessons. This is used in the information technology field and is found in many classrooms.
