A rhombus has an axis of symmetry through each pair of opposite vertex angles, while a rectangle has an axis of symmetry through each pair of opposite sides. The diagonals of a rhombus intersect at equal angles, while the diagonals of a rectangle are equal in length. See more In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are … See more A simple (non-self-intersecting) quadrilateral is a rhombus if and only if it is any one of the following: • a parallelogram in which a diagonal bisects an interior angle • a parallelogram in which at least two consecutive sides are equal in length See more The length of the diagonals p = AC and q = BD can be expressed in terms of the rhombus side a and one vertex angle α as $${\displaystyle p=a{\sqrt {2+2\cos {\alpha }}}}$$ and See more As for all parallelograms, the area K of a rhombus is the product of its base and its height (h). The base is simply any side length a: $${\displaystyle K=a\cdot h.}$$ The area can also be expressed as the base See more The word "rhombus" comes from Ancient Greek: ῥόμβος, romanized: rhombos, meaning something that spins, which derives from the verb See more Every rhombus has two diagonals connecting pairs of opposite vertices, and two pairs of parallel sides. Using congruent triangles, one can prove that the rhombus is symmetric across each of these diagonals. It follows that any rhombus has the following properties: See more The inradius (the radius of a circle inscribed in the rhombus), denoted by r, can be expressed in terms of the diagonals p and q as $${\displaystyle r={\frac {p\cdot q}{2{\sqrt {p^{2}+q^{2}}}}},}$$ or in terms of the … See more WebApr 6, 2024 · An object may have 0, 1 or more than one axes of symmetry. An axis of symmetry is also sometimes called a line of symmetry. For example, the letters A and M, each have a vertical axis of symmetry, the …
