(i) (2, 3), (4, 1)
(ii) (–5, 7), (–1, 3)
(iii) (a, b), (–a, –b)

Ans.

(i) Distance between the two points (x1, y1) and (x2, y2) is given by the expression x2x12+y2y12.Therefore, distance between points (2, 3) and (4, 1)           =422+132=4+4=22 units(ii) Distance between the two points (x1, y1) and (x2, y2) is given by the expression x2x12+y2y12.Therefore, distance between points (5, 7) and (1, 3)           =5(1)2+732=16+16=42 units(iii) Distance between the two points (x1, y1) and (x2, y2) is given by the expression x2x12+y2y12.Therefore, distance between points (a, b) and (a, b)           =a(a)2+b(b)2=4a2+4b2=2a2+b2

Q.2 Find the distance between the points (0, 0) and (36, 15). Can you now find the distance between the two towns A and B discussed in Section 7.2.

Ans.

Distance between points (0, 0) and (36, 15)           =(036)2+(015)2=1296+225=1521=39  unitsYes, we can find the distance between the given towns A and B.Let town A be at (0, 0) and town B be at (36, 15). Then, as perabove calculation, distance between the two towns is 39  km.

Q.3 Determine if the points (1, 5), (2, 3) and (– 2, –11) are collinear.

Ans.

Let the given points are P(1, 5), Q(2, 3) and R(2,11).Now, using distance formula we find distance between thesepoints i.e., PQ, QR and PR.Distance between points P(1, 5) and Q(2, 3)     =PQ=(12)2+(53)2=1+4=5Distance between points Q(2, 3) and R(2,11)    =QR=(2+2)2+(3+11)2=16+196=212=253Distance between points P(1, 5) and R(2,11)    =PR=(1+2)2+(5+11)2=9+256=265Now,           PQ+QR=5+253265=PRi.e., PQ+QRPRTherefore, points P(1, 5), Q(2, 3) and R(2,11) arenot collinear.

Q.4 Check whether (5, –2), (6, 4) and (7, –2) are the vertices of an isosceles triangle.

Ans.

Let the given points are P(5, 2), Q(6, 4) and R(7,2).Now, using distance formula we find distance between thesepoints i.e., PQ, QR and PR.Distance between points P(5, 2) and Q(6, 4)     =PQ=(56)2+(24)2=1+36=37Distance between points Q(6, 4) and R(7,2)    =QR=(67)2+(4+2)2=1+36=37Distance between points P(5, 2) and R(7,2)    =PR=(57)2+(2+2)2=4+0=2Now,           PQ+QR=37+372=PRi.e., PQ+QRPRTherefore, points P(5, 2), Q(6, 4) and R(7,2) arenot collinear. They form an isosceles triangle as lengths of sides PQ and QR are equal.

Q.5 In a classroom, 4 friends are seated at the points A, B, C and D as shown in the following figure. Champa and Chameli walk into the class and after observing for a few minutes Champa asks Chameli, “Don’t you think ABCD is a square?” Chameli disagrees. Using distance formula, find which of them is correct.


Ans.

It is given that 4 friends are seated at the points A(3, 4),B(6, 7), C(9, 4) and D(6, 1).Now, using distance formula we find length of each sideof the quadrilatral ABCD and diagonals AC and BD.AB=632+742=9+9=18=32,BC=692+742=9+9=18=32,CD=962+412=9+9=18=32,DA=632+412=9+9=18=32,AC=932+442=36+0=6,BD=662+712=0+36=6.We see that sides AB, BC, CD and DA are equal in lengths.Also, diagonals AC and BD are equal.Therefore, quadrilateral ABCD is a square. Hence, Champais correct.

Q.6 Name the type of quadrilateral formed, if any, by the following points, and give reasons for your answer:
(i) (–1, –2), (1, 0), (–1, 2), (–3, 0)
(ii) (–3, 5), (3, 1), (0, 3), (–1, –4)
(iii) (4, 5), (7, 6), (4, 3), (1, 2)

Ans.

(i)Let the given points are A(1, 2), B(1, 0), C(1, 2) andD(3, 0).Now, using distance formula we haveAB=(11)2+(20)2=4+4=22,BC=(1+1)2+(02)2=4+4=22,CD=(1+3)2+(20)2=4+4=22,DA=(1+3)2+(20)2=4+4=22andAC=(1+1)2+(22)2=0+16=4,BD=(1+3)2+(00)2=16+0=4.We see that sides AB, BC, CD and DA are equal in lengths.Also, diagonals AC and BD are equal.Therefore, the given points form a square.(ii)Let the given points are A(3, 5), B(3, 1), C(0, 3) andD(1, 4).Now, using distance formula we haveAB=(33)2+(51)2=36+16=52,BC=(30)2+(13)2=9+4=13,CD=(0+1)2+(3+4)2=1+49=52,DA=(1+3)2+(45)2=4+81=85We see that sides AB, BC, CD and DA are not equal.Therefore, the given points do not form a special quadrilateral. These points form a general quadrilateral.(iii)Let the given points are A(4, 5), B(7, 6), C(4, 3) and D(1, 2).Now, using distance formula we haveAB=(47)2+(56)2=9+1=10,BC=(74)2+(63)2=9+9=32,CD=(41)2+(32)2=9+1=10,DA=(41)2+(52)2=9+9=32andAC=(44)2+(53)2=0+4=2,BD=(71)2+(62)2=36+16=52.We see that opposite sides of quadrilateral ABCD are equal.But, diagonals AC and BD are not equal.Therefore, the given points form a parallelogram.

Q.7 Find the point on the x-axis which is equidistant from (2, –5) and (–2, 9).

Ans.

Let T(x, 0) be the point on the x-axis which is equidistant fromA(2, 5) and B(2, 9).Now, using distance formula we haveTA=(x2)2+(0+5)2=x24x+4+25=x24x+29andTB=(x+2)2+(09)2=x2+4x+4+81=x2+4x+85Now, TA=TBor    x24x+29=x2+4x+85or    x24x+29=x2+4x+85or    8x=2985=56or    x=7Hence, the required point is (7, 0).

Q.8 Find the values of y for which the distance between the points P(2, – 3) and Q(10, y) is 10 units.

Ans.

It is given that the distance between the points P(2, 3) and(10, y) is 10 units.Therefore, using distance formula we have        (210)2+(3y)2=10or    64+9+6y+y2=100or    y2+6y27=0or    y2+9y3y27=0or    y(y+9)3(y+9)=0or    (y3)(y+9)=0or    y=3 or  y=9

Q.9 If Q(0, 1) is equidistant from P(5, –3) and R(x, 6), find the values of x. Also find the distances QR and PR.

Ans.

It is given that Q(0, 1) is equidistant from P(5, 3) and R(x, 6). Therefore, using distance formula, we have        (05)2+(1+3)2=(0x)2+(16)2or    25+16=x2+25or    x2=16or    x=±4When x=4, thenQR=(04)2+(16)2=41 unitsandPR=(54)2+(36)2=82 unitsWhen x=4,  thenQR=(0+4)2+(16)2=41 unitsandPR=(5+4)2+(36)2=92 units

Q.10 Find a relation between x and y such that the point (x, y) is equidistant from the point (3, 6) and (–3, 4).

Ans.

It is given that the point (x, y) is equidistant from thepoint (3, 6) and R(3, 4).Therefore, using distance formula, we have        (x3)2+(y6)2=(x+3)2+(y4)2or    x26x+9+y212y+36=x2+6x+9+y28y+16or   6x6x12y+8y+4525=0or    12x4y+20=0or    3x+y5=0
