Perpendicular Lines in Algebra, Part II
Perpendicular lines are lines that intersect each other at right angles. In this video, Sal Khan demonstrates how to know which lines are perpendicular when solving an algebraic equation. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.  (03:28) There is a lot of information on the screen--the viewer may want to open the video to 'full screen.'
