Question

In the coordinate plane, three vertices of rectangle HDK are H(0, 0), (0, d), and Kle, 0). What are the coordinates of point J?

Answer 1

K = (e, d)

Explanation:

We are given the coordinates of three vertices of a rectangle and we are to find the coordinates of the fourth point J.

H (0, 0)

I (0, d)

K (e, 0)

J = ?

We can find this using the following formula:

K = H + (I - H) + (K - H)

K = H + I - H + K - H

K = I + K - H

Substituting the given values in it to get:

K =
`(0, d) + (e, 0) - (0, 0)`

K =
`(0+e-0, d+0-0)`

K = (e, d)
