To solve this problem, we need to identify the coordinates of a fourth point that will form a rectangle with the three marked points.

### Step-by-step solution:

The three points marked on the grid are approximately:
- Point A: (-4, 5)
- Point B: (2, 5)
- Point C: (-4, -5)

These three points can be seen as the three vertices of a rectangle. Now, let's find the fourth point, Point D.

1. **Observing the vertical and horizontal alignment:**
   - Points A and B are horizontally aligned (same y-coordinate: 5).
   - Points A and C are vertically aligned (same x-coordinate: -4).

2. **Using symmetry to find Point D:**
   - Since Points A and C are vertically aligned, the fourth point (Point D) must be horizontally aligned with Point C, meaning Point D should have the same y-coordinate as Point C, which is -5.
   - Since Points B and A are horizontally aligned, Point D must have the same x-coordinate as Point B, which is 2.

Thus, the coordinates of the fourth point are:
\[ D(2, -5) \]

This point completes the rectangle.

### Final Answer:
The coordinates of the fourth point are \( (2, -5) \).

Would you like a detailed breakdown of how rectangles are formed on a coordinate plane, or do you have further questions? Here are some related questions to consider:

1. How can we use the midpoint to verify a rectangle on a coordinate plane?
2. How do we calculate the area of a rectangle using coordinates?
3. What is the difference between a square and a rectangle in terms of coordinate geometry?
4. How can we find the perimeter of the rectangle formed by these four points?
5. What would change if the figure were a parallelogram instead of a rectangle?

**Tip:** When solving geometric problems on a coordinate grid, always check for patterns in the alignment of points (e.g., identical x- or y-coordinates) to find missing vertices.

Three points are marked on the coordinate grid. Find the coordinates of a fourth point so that the four points form the vertices of a rectangle.
