1. Let's clarify the problem: You mentioned that from 4 to 8 it is not a rectangle. We need to understand what shape or figure is being discussed and what properties define a rectangle. 2. A rectangle is a quadrilateral with four right angles and opposite sides equal in length. 3. If the figure from 4 to 8 does not have these properties, it cannot be a rectangle. 4. To verify, check the lengths of the sides between points 4 and 8 and the angles formed. 5. If the sides are not equal or the angles are not 90 degrees, then the shape is not a rectangle. 6. Without specific coordinates or a diagram, we cannot definitively conclude, but the key is to verify side lengths and angles. 7. If you provide more details or coordinates, I can help calculate and confirm the shape type.
