Question

A(3,3),B(3,6), and C(7,6) are three vertices of a rectangle.What are the coordinates of the fourth vertex of the rectangle?

Answer 1

In rectangle opposite sides are congruent; Let the fourth vertex be D (x, y)

Now in rectangle ABCD, side AB = side CD
Hence distance between AB and distance between CD will be equal
so d(A,B)=d(C,D)
Use here distance formula
