Answer:
the coordinates of the fourth vertex is (5,6)
Explanation:
Three of the vertices of a square are the points whose coordinates are (2, 3), (2, 6), and (5, 3).
All the sides are equal in a square.
LEts find the distance between (2, 3) and (2, 6)
To find the distance we subtract the y values

Side length is 3
To get the fourth vertex, we add 3 with (5,3) on y
(5,3+3) is (5,6)
the coordinates of the fourth vertex is (5,6)
