A rhombus, by definition, must be equilateral. Therefore, an isosceles rhombus cannot exist and so it cannot be a parallelogram.
No, they cannot.
No, it cannot. A rhombus has 4 sides, an octagon has 8.
a rhombus and a square. a square can be a parallelogram but a parallelogram cannot be a square. a rhombus cannot be a square but a square can be a rhombus. * * * * * A rhombus does not have any lines of symmetry, only a square has two.
No, a triangle cannot be a rhombus. A triangle is a polygon with three sides, while a rhombus is a polygon with four sides of equal length. These two shapes have different properties and cannot be the same.
The diagonals of a rhombus cannot be the same size.
A rhombus cannot be a cyclic quadrilateral because its opposite angles are not supplementary (unless it is a square). It cannot, therefore, have a radius.
The area of a rhombus cannot be determined form its side lengths. The shape can be flexed into a square (when it has maximum area) to a long thin rhombus (when it has minimum area).The area of a rhombus cannot be determined form its side lengths.

No, you cannot.
No, it cannot.
No. While a rhombus is a quadrangle which cannot have a right angle, that, in itself, is not enough.
A rhombus normally has no right angles (at the vertices). If a rhombus has right angles (at the vertices), it is called a square. The diagonals of a rhombus meet at right angles.
