## RD Sharma Class 11 Solutions Chapter 23 - The Straight Lines Exercise 23.17 - Free PDF

Class 11 chapter the straight line is a chapter based on geometry this chapter deals with coordinate geometry. This chapter can only be studied if the student has cleared his or her concepts of geometry taught in earlier classes like coordinate axis, coordinate plane, Plotting of points in a plane, the distance between two points, section formula. These are just the basic foundations of geometry and an understanding of these is required if a student wants to ace this chapter called the straight line. A straight line can simply be defined as a line in geometry that has zero width and a line that extends on both sides.

RD Sharma provides an extensive number of numerical questions that are based on this chapter of geometry. Solving these practise questions will increase the student’s ability to solve them in a time-efficient manner and will also help to clear their concepts on geometry. The expert mathematics teachers at Vedantu Have done extensive research and curated the solutions of the practice questions in the RD Sharma book of class 11 mathematics. Vedantu has solutions for all the chapters of the RD Sharma book, not only for class 11, the solutions can be easily accessed for classes 6 to 12 of the RD Sharma book.
