A rhombus has rotational symmetry. It is a symmetric shape that can be rotated and still appear the same. A rhombus has two-fold symmetry, meaning that is can be rotated 180 degrees and appear the same.
A rhombus is a parallelogram with four equal sides. This definition includes squares, which have additional forms of rotational symmetry. A rhombus has equal and opposite acute angles and equal and opposite obtuse angles. When working with rotational symmetry, it is common to focus on just the overall shape of the object and not any patterns or colors, as this could affect the result.
