Question

A base of a parallelogram is on the x-axis and the origin is located at the left endpoint of that base. Three consecutive vertices are (h, j), (0, 0), and (k, 0), where h > 0.

What, in terms of k and h, is the x-coordinate of the fourth vertex?

Answer 1

x coordinate= 0-(k-h)

Answer 2

hence -k+h
