For the parallelogram, find coordinates for P without using any new variables.

(a, b)
(1 point)
(а - с. с)
• (c, а)
(a - c. 0]
• (0, 0)

The coordinates for point P in the parallelogram can be found using the coordinate system.

Since P lies on the side formed by points (a, b) and (c, a), the x-coordinate of P would be the average of the x-coordinates of these two points, which is (a + c)/2.

Similarly, since P lies on the side formed by points (a, b) and (c, a), the y-coordinate of P would be the average of the y-coordinates of these two points, which is (b + a)/2.

Therefore, the coordinates for point P in the parallelogram are ((a + c)/2, (b + a)/2).
