Understanding parallel and perpendicular lines is a fundamental concept in Geometry, essential for analyzing angles, slopes, and coordinate plane relationships. Two lines are parallel if they have the same slope:
$ m_1 = m_2 $and perpendicular if the product of their slopes is $-1$: $ m_1 \times m_2 = -1 $
This Worksheet on Parallel and Perpendicular Lines provides clear examples, step-by-step explanations, and a variety of practice problems. By completing this worksheet, students will strengthen their skills in identifying, graphing, and calculating properties of parallel and perpendicular lines, building a solid foundation for more advanced geometry and algebra topics.
