Assuming that each vertex is used to connect exactly two sides, all two-dimensional shapes will have the same number of sides as vertices. So a shape with 4 sides will have 4 vertices and a shape with 3 sides will have 3 vertices. Think of a square (4 sides, 4 vertices) and a triangle (3 sides, 3 vertices).
That's true of every rhombus with less than 4 right angles.Also, every polygon with more than four sides can have 4 equal ones,but doesn't need to.
a hexagon * * * * * or any one of infinitely many polygons with 5 or more sides; any one of an infinite number of polyhedra with more than 4 faces, as well as other shapes that do not fit into these classifications: for example, a closed plane shape with five curved sides which meet pairwise.
A quadrilateral is a 2D shape that has 4 sides
A parallelogram that isn't a rhombus, rectangle, or square has. Any polygon with more than 4 sides could also have.
