I can't see the figure — could you upload the picture or describe the quadrilateral (e.g. square, rectangle, kite, parallelogram, labelled side/angle info)?
A few quick facts to help:
- Rotational symmetry angles must divide 360°, so the only choices here that are possible for a quadrilateral are 90° (order 4), 180° (order 2), or 360° (order 1, i.e. no nontrivial rotation).
- 60° is impossible for any quadrilateral because 360/60 = 6 would require 6-fold symmetry.
- Examples: a square → minimum angle 90°; a non-square rectangle or most parallelograms/rhombi → 180°; an irregular quadrilateral with no rotational symmetry → 360°.
Send the figure or describe it and I’ll pick the correct choice.
