Find the Coordinates of Points A, B, C, D in Fig. 27.7. - Mathematics

Find the coordinates of points A, B, C, D in Fig. 27.7.

Answer in Brief

Draw perpendiculars AP, BP, CQ and DR from A, B, C and D on the x-axis. Also, draw perpendiculars AW, BX, CY and DZ on the y-axis.

From the figure, we have:
AW = 1 unit and AP= 1 unit
So, the coordinates of vertex A are (1, 1).

Similarly, BX=1 unit and BP= 4 units
So, the coordinates of vertex B are (1, 4).
CY = 4 units and CQ= 6 units

So, the coordinates of vertex B are (4, 6).
DZ = 5 units and DR= 3 units
So, the coordinates of vertex B are (5, 3).

Exercise 27.1 | Q 4 | Page 6

State whether True or False. Correct those are false.

A point whose x coordinate is zero and y-coordinate is non-zero will lie on the y-axis.

Locate the points:

(1, 4), (2, 4), (3, 4), (4, 4).

Decide which of the following statements is true and which is false. Give reasons for your answer.

A point whose y-coordinate is zero, will lie on x-axis.

The coordinates of the origin are (0, 0).

Match the ordinates of the points given in Column A with the items mentioned in Column B.

Column A	Column B
(a) (7, 0)	(i) The ordinate is double the abscissa.
(b) (11, 11)	(ii) The ordinate is zero.
(c) (4, 8)	(iii) The ordinate is equal to the abscissa.
(d) (6, 2)	(iv) The abscissa is double the ordinate.
(e) (0, 9)	(v) The abscissa is triple the ordinate.
(f) (6, 3)	(vi) The abscissa is zero.
