Answer :

We have the required coordinates as follows:

For rectangle OABC are:

O(0, 0), A(2, 0), B(2, 3), C(0, 3)

For parallelogram PQRS:

P(4, 3), Q(6, 1), R(6, 5), S(4, 7)

For triangle KLM :

K(10, 5), L(7, 7), M (10, 8).

- 1.Plot the following points on a graph sheet. Verify if they lie on a line. (a) A (4, 0), B(4, 2), C(4, 6), D(4, 2.5) (b) P(1, 1), Q(2, 2), R(3, 3), S(4, 4) (c) K(2, 3), L(6, 3), M(5, 5), N (2, 5)
- 2.Draw the line passing through (2, 3) and (3, 2). Find the coordinates of the points at which this line meets the x-axis and y-axis.
- 4.State whether True or False. Correct that is false. (i) A point whose x-coordinate is zero and y-coordinate is non-zero will lie on the y-axis. (ii) A point whose y-coordinate is zero and x-coordinate is 5 will lie on y-axis. (iii) The coordinates of the origin are (0, 0).
