Question 1. \nFind the coordinates of the point which divides the join of (-1, 7) and (4, -3) in the ratio 2 : 3. \nSolution: \n <\/p>\n
Question 2. \nFind the coordinates of the points of trisection of the line segment joining (4, -1) and (-2, -3). \nSolution: \nLet P (x1<\/sub>, y1<\/sub>) and Q (x2<\/sub>, y2<\/sub>) be the points of trisection of A (4, -1) and B (- 2, – 3). \n \nTherefore, P divides AB internally in the ratio of 1.2. Therefore, by section formula coordinates of P are \n \nNow, Q also divides AB internally in the ratio 2 : 1, so the coordinates of Q are \n \nTherefore, the coordinates of the points of trisection of the line segment joining A and B are (2, \\(\\frac { 5 }{ 3 }\\)) and (0, \\(\\frac { 7 }{ 3 }\\))<\/p>\n <\/p>\n
Question 3. \nTo conduct Sports Day activities, in your rectangular shaped school ground ABCD, lines have been drawn with chalk powder at a distance of 1 m each. 100 flower pots have been placed at a distance of 1 m from each other along AD, as shown in given figure below. Niharika runs \\(\\frac { 1 }{ 4 }\\) the distance AD on the 2nd line and posts a green flag. Preet runs \\(\\frac { 1 }{ 5 }\\) th distance AD on the eighth line and posts a red flag. What is the distance between both the flags? If Rashmi has to post a blue flag exactly halfway between the line segment joining the two flags, where should she post her flag? \nSolution: \nIf the position of Niharika be M and the position of Preet by N the coordinate of point M are (2, 25) and the coordinate of point N are (8, 20) Distance between M and N are \n \nRashmi has to post a blue flag exactly halfway between the line MN. Suppose this point is 0. Then O divides the line MN at the ratio 1 :1 \nSo, the coordinate of point O (x1<\/sub>, x2<\/sub>) \n \nThe coordinate of O are (5, 22.5) \n\u2234 The position of the blue flag is 5th line at a distance of 22.5 m<\/p>\nQuestion 4. \nFind the ratio in which the line segment joining the points (-3, 10) and (6, -8) is divided by (-1, 6). \nSolution: \nLet the required ratio be k : 1 \n <\/p>\n
Question 5. \nFind the ratio in which line segment joining A (1, -5) and B (-4, 5) is divided by the x-axis. Also, find the coordinates of the point of division. \nSolution: \n <\/p>\n
<\/p>\n
Question 6. \nIf (1, 2), (4, y), (x, 6) and (3, 5) are the vertices of a parallelogram taken in order, find x and y. \nSolution: \n <\/p>\n
Question 7. \nFind the coordinates of a point A, where AB is the diameter of a circle whose centre is (2, -3) and B is (1, 4). \nSolution: \n <\/p>\n
Question 8. \nIf A and B are (-2, -2) and (2, -4), respectively, find the coordinates of P such that AP = \\(\\frac { 3 }{ 7 }\\) AB and P lies on the line segment AB. \nSolution: \n <\/p>\n
<\/p>\n
Question 9. \nFind the coordinates of the points which divide the line segment joining A (-2, 2) and B (2, 8) into four equal parts. \nSolution: \n <\/p>\n
Question 10. \nFind the area of a rhombus if its vertices are (3, 0), (4, 5), (-1, 4) and (-2, -1) taken in order. \n[Hint: Area of a rhombus = \\(\\frac { 1 }{ 2 }\\) (product of its diagonals)] \nSolution: \n <\/p>\n","protected":false},"excerpt":{"rendered":"
