Question

In the coordinate plane, three vertices of rectangle ABCD are A(0, 0), B(0, a), and D(b, 0). What are the coordinates of point C?

(2a, 2b)


(b, a)


(a, b)


(2b, 2c)

Answer 1

ans is (b, a)
although we dont kn the values of a and b,
the x coordinate of c must be same as point D,and y coordinate of C must be same as point B.U can draw a graph to help urself understand better
