In rectangle abcd, if the coordinates of a are (0, 0) and of c are (r, s), find the coordinates of b. (0, s) (s, 0) (0, r)

ANSWER

(0,s)

EXPLANATION

The coordinates of vertex A of rectangle ABCD is A(0,0) and that of C(r,s).

When we name the rectangle in anticlockwise direction, then B will have coordinates (0,s).

The reason is that, the x-coordinate of B will be the same as the x-coordinate of A, because they are on the same vertical line.

The y-coordinate of B is the same as the y-coordinate of C because they are on the same horizontal line.
