is a parallelogram.

The vertices of the parallelogram are and .

Find the coordinates of .

Since is a parallelogram,  must be parallel to .

Therefore, the -coordinate of must be the same as the -coordinate for .

So, the -coordinate of must be .

Also, since is a parallelogram, must be congruent to .

Since  is located at the origin and lies on the -axis, the length of is .

So, the length of  must also be .

Since  runs parallel to the -axis and begins at the -coordinate ,  will extend to the

-coordinate .

Therefore, the -coordinate of must be .

Point is located at .

Option D is correct.
