Question

A rectangle has vertices at these corrdinates (1, 2), (3, 2), (1, -8)

What are the coordinates of the fourth vertex of the rectangle

Answer 1

1,3

Explanation:

for K12

Answer 2

(3,-8)

Explanation:

Graph the points on the coordinate plane. Since a rectangle has equal sides with 90 degree angles, the last point will be below (3,2) at the same level as (1,-8). This point is (3,-8).
