From the given figure, answer the following question. Write the points whose abscissa is 0 .

Given, We know, The abscissa and ordinate are used to represent the position of a point on a graph. The distance of a point from y - axis scaled with the x - axis is called abscissa or x coordinate of the point. The distance of a point from x - axis scaled with the y - axis is called ordinate. The abscissa and ordinate all together are called coordinates. We need to find the points whose abscissa is 0 . The points those lie on y - axis have their abscissa as zero. Therefore, we get: A 0 , 3 , L 0 , - 4 and O 0 , 0 Hence, the points are A , L and O .

From the given figure, answer the following question. Write the points whose ordinate is 0 .

Given, We know, The abscissa and ordinate are used to represent the position of a point on a graph. The distance of a point from y - axis scaled with the x - axis is called abscissa or x coordinate of the point. The distance of a point from x - axis scaled with the y - axis is called ordinate. The abscissa and ordinate all together are called coordinates. We need to find the points whose ordinate is 0 . The points those lie on x - axis have their ordinate as zero. Therefore, we get: I - 2 , 0 , G 5 , 0 and O 0 , 0 Hence, the points are I , G and O .

From the given figure, answer the following question. Write the points whose abscissa is - 5 .

Given, We know, The abscissa and ordinate are used to represent the position of a point on a graph. The distance of a point from y - axis scaled with the x - axis is called abscissa or x coordinate of the point. The distance of a point from x - axis scaled with the y - axis is called ordinate. The abscissa and ordinate all together are called coordinates. We need to find the points whose abscissa is - 5 . Therefore, we get: D - 5 , 1 , H - 5 , - 3 Hence, the points are D and H .

In the given figure, A B C D is a rhombus with diagonals A C = 16 cm and B D = 8 cm . Find the coordinates of A , B , C and D .

Given, A B C D is a rhombus with diagonals A C = 16 cm and B D = 8 cm . We know, The diagonals of a rhombus bisect each other at right angles. Thus, we get: A C = A O + O C = 16 cm ⇒ A O = O C = 8 cm And, B D = B O + O D = 8 cm ⇒ B O = O D = 4 cm Therefore, we get the coordinates according to their corresponding quadrants as follows: A lies on the negative direction of x - axis and the coordinates are - 8 , 0 B lies on the positive direction of y - axis and the coordinates are 0 , 4 C lies on thepositive direction of x - axis and the coordinates are 8 , 0 D lies on the negative direction of y - axis and the coordinates are 0 , - 4 Hence, the points are A - 8 , 0 , B 0 , 4 , C 8 , 0 and D 0 , - 4 .
