10th CBSE math solution for exercise 7.2

(1) Find the coordinates of the point which divides the join of (-1,7) and (4,-3) in the ratio 2 : 3.   Solution

(2) Find the coordinates of the points of trisection of the line segment joining (4,-1) and (-2,-3).  Solution

(3) To conduct sports day activitie,in your rectangular shaped school ground ABCD, lines have been drawn which 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 fig 7.12. Niharika runs ΒΌ th the distance AD on the second line and posts a green flag. Preet runs 1/5th the distance AD on the eight line and posts a red flag. What  is 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?  Solution

(4) Find the ratio in which the line segment joining the points (-3,10) and (6,-8) is divided by (-1,6).  Solution

(5) Find the ratio in which the 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. Solution

(6) If (1,2),(4,y) (x,6) and (3,5) are the vertices of a parallelogram taken in order,find x and y Solution

(7) Find the coordinates of a point A,where AB is the diameter of a circle whose center is (2,-3) and B(1,4) Solution

(8) If A and B are (-2,-2) and (2,-4),respectively,find the coordinates of P such that AP = (3/7) AB and P lies on the line segment AB. Solution

(9) Find the coordinates of the points which divide the line segment joining A (-2,2) and B(2,8) into four equal parts. Solution

(10) Find the area of a rhombus if its vertices are (3,0) (4,5) (-1,4) and (-2,-1) taken in order.[Hint:Area of rhombus = (1/2) product of its diagonals] Solution
