✓ 1. Try constructing a vertical line of symmetry by dragging the points on the dashed line to W and Y.
✓ 2. Press Fold to reflect the rectangle over the dashed line.
✓ 3. The rectangle has vertical symmetry because the left and right halves are mirror images. Press Continue for the next step.
✓ 4. Try constructing a horizontal line of symmetry by dragging the points on the dashed line to Z and X.
✓ 5. Press Fold to reflect the rectangle over the dashed line.
✓ 6. The rectangle has horizontal symmetry because the top and bottom halves are mirror images. Press Continue for the next step.
✓ 7. Try constructing a diagonal line of symmetry by dragging the points on the dashed line to A and C.
✓ 8. Press Fold to reflect the rectangle over the dashed line.
✓ 9. Does the rectangle have diagonal symmetry?
✓ 10. What is the n-fold symmetry of the rectangle?
