QUESTION: 1

The distance between the points (a, b) and (– a, – b) is :

Solution:

We have distance formula as d = 
Where x1=a,y1=b,x2=-a,y2=-b

QUESTION: 2

The distance between points (a + b, b + c) and (a – b, c – b) is :

Solution: Distance between two point is
root[{(a+b)-(a-b)}^2] + [{(b+c)-(c-b)}^2]
=root [{(a+b-a+b)^2}] + [((b+c-c+b)}^2]
=root[(2b)^2 + (2b)^2]
=root[4b^2 +4b^2]
=root[8b^2]
=2.root(2)b
QUESTION: 3

The distance between A (1, 3) and B (x, 7) is 5. The value of x > 0 is :

Solution:
QUESTION: 4

The distance between the points (a cos 20° + b sin 20°, 0) and (0, a sin 20° – b cos 20°) is :

Solution:
QUESTION: 5

Mid-point of the line-segment joining the points (– 5, 4) and (9, – 8) is :

Solution:
QUESTION: 6

The co-ordinates of the points which divides the join of (– 2, – 2) and (– 5, 7) in the ratio 2 : 1 is :

Solution:
QUESTION: 7

The co-ordinates of the point on x-axis which is equidistant from the points (5, 4) and (– 2, 3) are :

Solution:

Let the point on x-axis be (a,0)
Since PA = PB  PA2 = PB2
 (a + 2)2 + (0 - 5)2 = (a - 2)2 + (0 + 3)2
 (a + 2)2 - (a - 2)2 = 9 - 25 = -16
 8a = -16  a = -2.
 The required point is (-2,0).

QUESTION: 8

The co-ordinates of the point on y-axis which is equidistant from the points (3, 1) and (1, 5) are:

Solution:
QUESTION: 9

The coordinates of the centre of a circle are (– 6, 1.5). If the ends of a diameter are (– 3, y) and (x, – 2) then:

Solution:
QUESTION: 10

The points (– 2, 2), (8, – 2) and (– 4, – 3) are the vertices of a :

Solution:
QUESTION: 11

The points (1, 7), (4, 2), (– 1, 1) and (– 4, 4) are the vertices of a :

Solution:

Step-by-step explanation:

Given points are (1,7),(4,2),(-1,-1),(-4,4)

Let the points are A,B,C,D.

Distance formula = √(x₂-x₁)²+(y₂-y₁)²

                   AB = √(4-1)²+(2-7)²

                         = √9+25

                         = √34

                    BC = √(-1-4)²+(-1-2)²

                          = √25+9

                          =  √34

                     CD = √(-4-(-1))²+(4-(-1))²

                           = √9+25

                           =  √34

                      DA = √(1-(-4))²+(7-4)²

                            = √25+9

                            = √34

also diagonals AC and BD

AC = √(1+1)² + (7+1)² = √68

BD = √(4+4)² + (2-4)² = √68

We know that the all sides and both diagonals of the square are equal

So,from this we can say that these points are the vertices of a square.

QUESTION: 12

The line segment joining (2, – 3) and (5, 6) is divided by x-axis in the ratio:

Solution:
QUESTION: 13

The line segment joining the points (3, 5) and (– 4, 2) is divided by y-axis in the ratio:
