Four sides of equal length. All other properties follow from this.
The answer is it must be a rhombus
It must be a rhombus
Not just often: any rhombus must be a parallelogram.
A rhombus must have exactly two obtuse angles.
All 4 sides of a rhombus must be equal, otherwise it's not a rhombus.
You cannot circumscribe a "true rhombus". The opposite angles of a circumscribed quadrilateral must be supplementary whereas the opposite angles of a rhombus must be equal. That means a circumscribed rhombus is really a square.
it must be a parallelogram
It must be a rhombus
A rhombus must have a pair of opposite angles which are obtuse (and equal).
A rhombus, by definition, must be equilateral. Therefore, an isosceles rhombus cannot exist and so it cannot be a parallelogram.
'Course they can, a square's a rhombus, right? * * * * * Not only can it, but it MUST.
Yes, A rhombus must ALWAYS have four sides no matter what!!
