An architect is trying to find the perfect place to build a "A" shaped bridge over a river. The left side of the bridge begins at (-9,-4) and the right side of the bridge is at (9,-4).
The top of the "A" shaped bridge will be located at (0,2). Sea-level (ground level) is when y = -4.

To prove that def ~ gfh by the sss similarity theorem using the information provided in the diagram, it would be enough additional information to know that
