Question

Three vertices of a rectangle are (3, 4), (5, 4), and (5, 2). What are the coordinates of the fourth corner point of the rectangle? A. (3, 4) B. (3, 2) C. (5, 3) D. (5, 2)

Answer 1

B. (3,2)
This is visible if you plot the points.
However, without plotting, this can be determined as well. The first two points have the same value of y meaning they form a horizontal line.
The second and third points have the same value of x meaning they form a vertical line. Now, we need a point that has the same y value (2) as the third point so it forms a horizontal line with it and the same value of x as the first point (3) so it forms a vertical line with it. That is, (3 , 2)
