Exercise 1.1 Class 9 Maths Solutions of Ganita Manjari helps students understand the basics of coordinate geometry. These new NCERT Ganita Manjari solutions are explained in simple language for CBSE students at sidclasses.in . All questions of class 9 maths chapter 1 Orienting yourself: The use of Coordinates are solved step by step for better understanding and exam preparation. These new NCERT Class 9 Maths solutions are prepared according to the latest CBSE syllabus.
Chapter 1 Orienting yourself: The use of Coordinates introduces the basic concepts of coordinate geometry. In this chapter, students learn how to locate points on a graph using the x-axis and y-axis. The point where both axes meet is called the origin.
Coordinate geometry helps us describe the exact position of objects using ordered pairs such as (x, y). In daily life, maps, GPS systems, and computer graphics also use coordinates to locate places and objects accurately.
Students can use these solutions to complete homework, revise concepts, and prepare for exams easily.

Exercise 1.1 Solutions – Orienting Yourself: The Use of Coordinates
Question 1
Fig. 1.3 shows Reiaan’s room with points OABC marking its corners. The x- and y-axes are marked in the figure. Point O is the origin.
Referring to Fig. 1.3, answer the following questions:
(i) If D1 R1 represents the door to Reiaan’s room, how far is the door from the left wall (the y-axis) of the room? How far is the door from the x-axis?
Since, D1 (8, 0) and R1 (11.5,0), So the door is 8 units away from y-axis.
Also, the door lies on the x-axis, it is 0 units away from the x-axis.
(ii) What are the coordinates of D1 ?
(iii) If R1 is the point (11.5, 0), how wide is the door? Do you think this is a comfortable width for the room door? If a person in a wheelchair wants to enter the room, will he/she be able to do so easily?
A person using a wheelchair can also enter the room easily through this door.
(iv) If B1 (0, 1.5) and B2 (0, 4) represent the ends of the bathroom door, is the bathroom door narrower or wider than the room door?
Width of bathroom door = 4 -1.5 = 2.5 units
Since 2.5 units is less than 3.5 units, the bathroom door is narrower than the room door.
