The problem you're working on involves identifying which of the figures are scaled copies of the original triangle labeled as "Figure A."

To determine whether a figure is a scaled copy, we need to check if the corresponding sides of the figures have proportional lengths and if the angles are congruent.

**Let's analyze each figure:**

1. **Figure 1** - This figure appears to be rotated but has the same shape and proportion as Figure A. Since rotation does not affect scaling, Figure 1 is likely a scaled copy of Figure A.

2. **Figure 2** - This figure seems to have larger side lengths but retains the shape and angle measures of Figure A. This suggests that Figure 2 is a scaled copy of Figure A.

3. **Figure 3** - This figure looks different in shape and orientation, and the proportions do not seem to match those of Figure A. This figure is likely **not** a scaled copy of Figure A.

4. **Figure 4** - This figure has the same orientation and shape as Figure A, but it might be smaller. If the side lengths are proportional, Figure 4 is a scaled copy of Figure A.

So, **Figures 1, 2, and 4** are scaled copies of the original triangle, Figure A.

### Related Questions:
1. How can you verify that two triangles are similar or scaled copies using side lengths and angles?
2. What transformations (like rotation, reflection, or translation) preserve the scale of a figure?
3. How does scaling affect the area of a figure compared to the original?
4. If Figure 4 was reflected instead of rotated, would it still be a scaled copy of Figure A?
5. How would the perimeter of a scaled copy compare to the perimeter of the original triangle?

### Tip:
When checking if two shapes are scaled copies, always verify both the proportionality of corresponding side lengths and the congruence of corresponding angles.
