Walkthrough
Full solution stays hidden until you ask for it.
1. Confirm two side pairs match between the triangles.
2. Compare the included angles or opposite sides.
3. Use the hinge relationship to state the conclusion.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Applying hinge theorem without two fixed side pairs.
