You are give points X
A (-1,-1)
B (-1,3)
C (3,3)
Coordinates are written: (x value, y value).
The horizontal axis gives us the x value and the vertical axis gives us the y value.
Plot the points above in alphabetical order. Then, identify the fourth point needed to create a square.
Write the coordinates of the fourth point D of the square.

Answer 1

Plot the points in alphabetical order: A (−1, −1), B (−1, 3), C (3, 3).

AB is a vertical segment of length 4 (vector (0,4)), BC is a horizontal segment of length 4 (vector (4,0)). The fourth vertex is A shifted by the same horizontal vector or C shifted down by 4:

D = (3, −1).
