MCQs for Coordinate Geometry

1.The points (- 1, – 2), (1, 0), (- 1, 2), (- 3, 0) forms a quadrilateral of type:

(a)Square

(b)Rectangle

(c)Parallelogram

(d)Rhombus

Answer: a

Explanation: Let A(- 1, – 2), B(1, 0), C(- 1, 2) and D(- 3, 0) are the four vertices of quadrilateral.

By distance formula, we know:

AB=(1+1)2+(0+2)2=22

BC=(11)2+(20)2=22

CD=(3+1)2+(02)2=22

DA=(3+1)2+(2)2=22

AC=(1+1)2+(2+2)2=4

BD=(1+3)2+(00)2=4

Hence, the length of the sides = 2√2

Diagonals = 4

Hence, the given points form a square.

2.If the distance between the points A(2, -2) and B(-1, x) is equal to 5, then the value of x is:

(a)2

(b)-2

(c)1

(d)-1

Answer: a

Explanation: By distance formula, we know:

9+(x+2)2=25

(2+x)2=16

Take square root on both the sides,

2+x=4

x=2

3.The midpoints of a line segment joining two points A(2, 4) and B(-2, -4)

(a) (-2,4)

(b) (2,-4)

(c) (0, 0)

(d) (-2,-4)

Answer: c

Explanation: As per midpoint formula, we know;

x=[2+(-2)]/2 = 0/2 = 0

y=[4+(-4)]/2=0/2=0

Hence, (0,0) is the midpoint of of AB.

4.The distance of point A(2, 4) from x-axis is

(a)2

(b)4

(c)-2

(d)-4

Answer: b

Explanation: Distance of a point from x-axis is equal to the ordinate of the point.

5.The distance between the points P(0, 2) and Q(6, 0) is

(a)4√10

(b)2√10

(c)√10

(d)20

Answer: b

Explanation: By distance formula we know:

PQ=(x2x1)2+(y2y1)2

PQ = √[(6-0)2+(0-2)2]

PQ = √(62+22)

PQ=√(36+4)

PQ=√40=2√10

6.If O(p/3, 4) is the midpoint of the line segment joining the points P(-6, 5) and Q(-2, 3). The value of p is:

(a)7/2

(b)-12

(c)4

(d)-4

Answer: b

Explanation: Since, (p/3, 4) is the midpoint of line segment PQ, thus;

p/3 = (-6-2)/2

p/3 = -8/2

p/3 = -4

p= -12

Therefore, the value of p is -12.

7.The points which divides the line segment of points P(-1, 7) and (4, -3) in the ratio of 2:3 is:

(a)(-1, 3)

(b)(-1, -3)

(c)(1, -3)

(d)(1, 3)

Answer: d

Explanation: By section formula we know:

x=[(2.4)+(3.(-1))]/(2+3) = (8-3)/5 = 1

y=[(2.(-3))+(3.7)]/(2+3) = (-6+21)/5 = 3

Hence, the required point is (1,3)

8.The ratio in which the line segment joining the points P(-3, 10) and Q(6, – 8) is divided by O(-1, 6) is:

(a)1:3

(b)3:4

(c)2:7

(d)2:5

Answer: c

Explanation: Let the ratio in which the line segment joining P( -3, 10) and Q(6, -8) is divided by point O( -1, 6) be k :1.

So, -1 = ( 6k-3)/(k+1)

–k – 1 = 6k -3

7k = 2

k = 2/7

Hence, the required ratio is 2:7.

9.The coordinates of a point P, where PQ is the diameter of circle whose centre is (2, – 3) and Q is (1, 4) is:

(a)(3, -10)

(b)(2, -10)

(c)(-3, 10)

(d)(-2, 10)

Answer: a

Explanation: By midpoint formula, we know;

[(x+1)/2,(y+4)/2] = (2,-3) (Since, O is the midpoint of PQ)

(x+1)/2 = 2

x+1=4

x=3

(y+4)/2 = -3

y+4=-6

y=-10

So, the coordinates of point P is (3, -10).

10.The area of a rhombus if its vertices are (3, 0), (4, 5), (-1, 4) and (-2,-1) taken in order, is:

(a)12 sq.unit

(b)24 sq.unit

(c)30 sq.unit

(d)32 sq.unit

Answer: 24

Explanation: To find the area of the rhombus, we need to find the length of its diagonals and use the below formula:

Area = ½ (Diagonal1)(Diagonal2)

Area = (1/2 ) (AC)(BD)

Diagonal1=√[(3-(-1))2+(0-4)2]= 4√2

Diagonal2 = √[(4-(-2))2+(5-(-1))2]=6√2

Area = ½ x 4√2 x 6√2 = 24 sq.unit.
