Rotational Symmetry of a Parallelogram: Clear Working out
Fun introduction to symmetry and a common geometry lies here. Parallelograms also include rhombuses when sides are equal, rectangle when angles are equal, and square when both sides and angles are equal. Once you see the rotational symmetry of a parallelogram, you can see the rotational symmetry of all 4 four-forms much simpler. How To […]
