Question Video: Understanding the Definition of the Projection of a Line Segment Mathematics • Second Year of Preparatory School

Video Transcript

Complete: The length of the projection of a line segment onto a line is blank the length of the line segment itself. Is it at least or at most the length of the line segment itself?

The length of the projection, if we say it’s at least the length of the line segment itself, if we say that the length of the projection is at least the length of the line segment, that means the length of the projection will be greater than or equal to the length of the line segment. And that is not true.

The length of the projection will always be less than or equal to the line segment, which means that the length of the projection of a line segment is at most the length of the line segment itself.
