![]() It has 10 faces on the polar axis with 10 faces following the equator. The rhombic icosahedron is a polyhedron composed of 20 rhombic faces, of which three, four, or five meet at each vertex.The rhombic enneacontahedron is a polyhedron composed of 90 rhombic faces, with three, five, or six rhombi meeting at each vertex.The distance (at right angles) from one base to the other is called the 'altitude'. It is nonconvex with 60 golden rhombic faces with icosahedral symmetry. A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel (marked with arrows below): is an isosceles trapezoid when it has equal angles from a parallel side. The rhombic hexecontahedron is a stellation of the rhombic triacontahedron.The great rhombic triacontahedron is a nonconvex isohedral, isotoxal polyhedron with 30 intersecting rhombic faces.The rhombic triacontahedron is a convex polyhedron with 30 golden rhombi (rhombi whose diagonals are in the golden ratio) as its faces. ![]() The rhombic dodecahedron is a convex polyhedron with 12 congruent rhombi as its faces.A rhombohedron (also called a rhombic hexahedron) is a three-dimensional figure like a cuboid (also called a rectangular parallelepiped), except that its 3 pairs of parallel faces are up to 3 types of rhombi instead of rectangles. A quadrilateral is a closed shape that is formed by joining four points among which any three points are non-collinear.In simple words, a quadrilateral is a polygon with 4 sides, 4 angles, and 4 vertices. A kite is a quadrilateral shape with two pairs of adjacent (touching), congruent (equal-length) sides.Because of this symmetry, a kite has two equal angles and two pairs of adjacent equal-length sides. Three-dimensional analogues of a rhombus include the bipyramid and the bicone as a surface of revolution.Ĭonvex polyhedra with rhombi include the infinite set of rhombic zonohedrons, which can be seen as projective envelopes of hypercubes. In Euclidean geometry, a kite is a quadrilateral with reflection symmetry across a diagonal.Identical rhombi can tile the 2D plane in three different ways, including, for the 60° rhombus, the rhombille tiling.One of the five 2D lattice types is the rhombic lattice, also called centered rectangular lattice.Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. In plane Euclidean geometry, a rhombus (PL: rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. K = p ⋅ q 2 This is a special case of the superellipse, with exponent 1. The rhombus has a square as a special case, and is a special case of a kite and parallelogram. Quadrilateral, trapezoid, parallelogram, kite
