A regular polygon must be equilateral (all of its sides are the same length) and equiangular (all of its angles are the same measure). A rhombus is equilateral: all of its sides are of the same length. But it is never equiangular. A rhombus by definition has two opposite sets of equal angles. read more
Yes, a rhombus is a polygon. A polygon is a closed figure composed of line segments, that only intersect at the end points of the line segments. any polygon with 4 sides is known as a quadrilateral. Any quadrilateral with all 4 sides equal in length is known as a Rhombus. So a rhombus is a polygon. read more
By definition: A polygon is any closed shape with no curves. A quadrilateral is any polygon that has 4 sides. A parallelogram is any quadrilateral that has two pairs of parallel sides. A rhombus is any parallelogram that has 4 equal sides. Therefore, a rhombus is a parallelogram, which is a quadrilateral, which is a polygon. read more
A rhombus is equilateral: all of its sides are of the same length. But it is never equiangular. A rhombus by definition has two opposite sets of equal angles. It can never, therefore, be equiangular. All of its angles cannot be the same or it would be a square, not a rhombus. A rhombus can never be a regular polygon because it is not equiangular. read more
