Problem 42 of 7
Determine the reflection symmetry of a trapezoid with congruent base angles.
Using a hint is okay. It just tells the trainer to give you a little more review.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Check whether the legs are congruent.
2. If the trapezoid is isosceles, identify the line through base midpoints.
3. If not, no reflection line maps it to itself.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Assuming every trapezoid has a symmetry line.
