By Amethyst boyd Parallel vs Perpendicular Parallel Equal distance between lines from top to bottom Never intersect Same slopes EXAMPLES Perpendicular Intersect forming 90 degree lines On same plane. Parallel and Perpendicular lines. Prepared by . Doron. . Shahar. Warm-up: page 29. Two lines are parallel if _____________________.. If two lines are parallel, then their slopes, . m. 1. and . m. 2. Methods in Graphing. Understanding Slope. AI.L.4: Represent linear functions as graphs from . equations, equations . from tables and other given . information. AI.L.7: . Solve linear . inequalities in two variables by graphing. Parallel and Perpendicular Lines. Perpendicular lines. are two lines that intersect to form a 90º. . angle. . Parallel and Perpendicular Lines. Parallel lines. are two lines that, if extended indefinitely, would never cross or touch. My math presentation of parallel and perpendicular lines… . And . mathiness. and history. These were from some ancient Roman or Greek guy. . H. is name was Euclid (for parallel). Though there was much talk about lines that crossed in a 90 degree way, the first time it was used in math was by a French philosopher named Cartesian.. Objective Learn to recognize parallel and perpendicular lines. . Parallel and Perpendicular Lines…. A . plane. is an infinite, flat surface. Lines in a plane that never meet are called . parallel Lines. Line Segments,. Rays. Line. Line- a straight path that goes in two directions without ending.. A. B. AB. Read: “Line AB”. Ray.
