We know there are four quadrants in a regular cartesian co-ordinate; in math worksheet on quadrants we will practice the basic questions on quadrants.

Recall the process to solve the questions given in the worksheet on quadrants;
x, y are real and positive then the point

Having co-ordinate (x, y) lies in the first quadrant,

Having co-ordinate (-x, y) lies in the second quadrant,

Having co-ordinate (-x, -y) lies in the third quadrant,

Having co-ordinate (x, -y) lies in the fourth quadrant.

1. In which quadrant do the following points lie?

(i) (2, - 7)

(ii) (√5 - 3, - 2)

(iii) (√2 - 1, 3 -√3)

(Iv) (- 5, √7- 2)

(v) (x, y).

2. Points Q, R and S lie on 1st, 2nd, 3rd and 4th quadrants respectively. If dm Minima of each of them from the co-ordinate axes be 6 and 4 units irspritively, write down their co-ordinates.

3. What do you mean by rectangular Cartesian co-ordinates of a point? What do you know about co-ordinates of points lying on x-axis and y-axis? Where do the following points lie?

(i) (4, 0) (ii) (0, - 6) (iii) (0, 3) (iv) (- 5, 0).

4. The sides of the rectangle ABCD are parallel to the co-ordinate axes. If the co-ordinates of the vertices B and D be (7, 3) and ( 2, 6) respectively, find the co-ordinates of the vertices A and C.

Answers for the worksheet on quadrants are given below to check the exact answers of the above questions.

(v) 1st quadrant if x and y are both positive; 2nd quadrant if x is negative and y positive; 3rd quadrant if x and y are both negative ;4th quadrant if x is positive and y negative

2. P(4, 6), Q (-4, 6) ,R (-4, -6),S (4, -6);

3. (i) on positive x-axis

(ii) on positive y-axis

(iii) on positive y-axis

(iv) on positive x-axis;

4. A(2, 3) and C(7, 6);
