All squares are rhombuses, but not all rhombuses are squares. A proof of this property of the diagonals. All parallelogram properties apply to rhombus properties since a rhombus is a type of parallelogram . The quadrilateral is basically of 6 types such as: A rhombus is a special case of a parallelogram, and it is a four-sided quadrilateral. When the shorter diagonal is equal to one of the sides of a rhombus, two congruent equilateral triangles are formed. Students use this applet to investigate the properties of a rhombus. A rhombus is a quadrilateral whose sides are all equal. Rhombus is also known as diamond or rhombus diamond is a parallelogram and a four- sided quadrilateral. Using Area of the rhombus formula,  A = (d1 x d2)/2 square units, we get. Substitute 14a + 20 for m VTZ. Every rhombus has 4 congruent sides so every single square is also a rhombus. Why? The diagonals bisect the vertex angles of a rhombus. Ask yourself: What is true about the angles formed by the diagonals of a rhombus? The diagonals of parallelograms bisect each other. \angle AOB = 90^{\circ} ACD = 12 + x In a rhombus, diagonals bisect each other at right angles. Example problems for rhombus properties: Example: 3 Determine the side of the rhombus whose perimeter value is 160 cm. and parallel, and the diagonals So, as it says a rhombus is also a parallelogram which means it has also inherited all the properties of a parallelogram and it is having all sides equal other than that. Also, the diagonals of a rhombus bisect these angles. Notice that the diagonals are perpendicular and the sum of the perpendicular angles is 360^\circ 360∘.
