The chapter “Straight Lines” in NCERT Class 11 Maths focuses on the geometry of lines in a plane and their equations. Students learn about different forms of line equations, including slope-intercept form, point-slope form, two-point form, and general form.
Key topics include distance of a point from a line, angle between two lines, condition of parallelism and perpendicularity, and applications in coordinate geometry. The chapter explains graphical representation of lines, helping students visualize and solve problems effectively.
With step-by-step derivations, solved examples, and exercises, students develop strong problem-solving and analytical skills.
This chapter is crucial for building a foundation in coordinate geometry and is highly useful for Class 11 exams, JEE, NEET, and other competitive entrance tests, where questions on straight lines frequently appear.
