Answer:
The coordinates of the fourth vertex of the rectangle is (3,-8).
Step-by-step explanation:
It is given that a rectangle has vertices at these coordinates. (1, 2) , (3, 2) , (1, −8).
Let the coordinates of the fourth vertex of the rectangle be (x,y).
The diagonals of rectangle intersect each other at their midpoint.
Plot these points on a coordinate plane. From the graph it is noticed that the end point of one diagonal are (3, 2) and (1, −8).
The end point of second diagonal are (1, 2) and (x,y).
Since the diagonals of rectangle intersect each other at their midpoint, therefore
On comparing both the sides,
Therefore the coordinates of the fourth vertex of the rectangle is (3,-8).
