Plot the points (–1, 0), (1, 0), (1, 1), (0, 2), (–1, 1), and which figure is obtained by joining these correctively.

Plot the points with following coordinates (1, 2), (–1, 3), (–2, –4), (3, –2), (2, 0), (0, 3).

Taking rectangular axes plot the points O(0, 0), P(3, 0) and R(0, 4). If OPQR is a rectangle, then find the coordinates of point Q.

Draw a quadrilateral, if its vertices are as follows:

(i) (1, 1), (2, 4), (8, 4) and (10, 1)

(ii) (–2, –2), (–4, 2), (–6, –2) and (–4, –6).

In each case tell the type of the quadrilateral.

Find the distance between the following points:

(i) (–6, 7) and (–1, –5)

(ii) (–1, –1) and (8, –2)

(iii) (at₁², 2at₁) and (at₂², 2at₂)
