Walkthrough
Full solution stays hidden until you ask for it.
1. Use the parallel sides to establish angle relationships.
2. Show opposite angles are corresponding parts or supplements of the same angle.
3. Conclude opposite angles are congruent.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Assuming opposite angles are congruent without support.
