Parallel and Perpendicular Lines

Parallel and perpendicular lines form the basis of many aspects of engineering and architecture. Without an understanding of these types of lines, it would be impossible to create building structures that stand upright on a solid foundation. In this topic, you will expand your knowledge of linear equations as you explore parallel and perpendicular lines.
