Chapter 3: Coordinate Geometry Exercise 3.10 solutions [Page 53]

Ex. 3.10 | Q 1 | Page 53

How will you describe the position of a table lamp on your study table to another person?

Ex. 3.10 | Q 2 | Page 53

(Street Plan) : A city has two main roads which cross each other at the centre of the city. These two roads are along the North-South direction and East-West direction.

All the other streets of the city run parallel to these roads and are 200 m apart. There are 5 streets in each direction. Using 1cm = 200 m, draw a model of the city on your notebook. Represent the roads/streets by single lines.

There are many cross- streets in your model. A particular cross-street is made by two streets, one running in the North - South direction and another in the East - West direction. Each cross street is referred to in the following manner : If the 2nd street running in the North - South direction and 5th in the East - West direction meet at some crossing, then we will call this cross-street (2, 5). Using this convention, find:-

(i) how many cross - streets can be referred to as (4, 3).

(ii) how many cross - streets can be referred to as (3, 4).

What is the name of each part of the plane formed by these two lines?

Ex. 3.20 | Q 1.3 | Page 60

Write the answer of each of the following questions:-

Write the name of the point where these two lines intersect.

Ex. 3.20 | Q 2 | Page 60
