Problem 33 of 7
Identify the symmetries of a parallelogram where only opposite sides are equal in length and no angles are 90 degrees.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
distinguish rotational symmetry from reflection symmetry.
Hidden until you reveal it.
Parallelogram type must be specific enough to determine standard symmetries.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify whether the parallelogram has special properties.
2. All parallelograms have 180-degree rotational symmetry.
3. Add reflection or 90-degree symmetries only for special cases.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Giving rectangle reflection symmetries to every parallelogram.
