A rhombus always has four equal sides and two pairs of parallel sides. It may have either two obtuse angles or no obtuse angles. If it has no obtuse angles, then that particular rhombus also qualifies as a square.
Yes. (and more).
On squares and rectangles, yes. But on parallelograms and rhombus the one diagonal can be shorter than one of the sides.
More than one Rhombus
A rhombus is a shape with one pair of parallel sides. I has four sides and angles.
Yes, it is one of the ways to prove a figure is a rhombus. If adjacent sides are congruent, then the figure is a rhombus.
No, a rhombus can never be a trapezoid. A trapezoid has one pair of parallel sides, and a rhombus has two pairs of parallel sides.
A trapezoid has one pair of parallel sides, a rhombus has two.A trapezoid can have at most three sides of equal length, though it need not have any. All four sides of a rhombus must be the same length.
An equilateral triangle. For polygons with 4 or more sides there are more than one possiblilities (square and rhombus for quadrilaterals) and there is no single name for such shapes. "Regular" requires equal angles which is NOT a requirement of the question.
The sides of a rhombus are all equal.
It is an impossible figure. It is either a rhombus and has two pair of opposite sides that are parallel, or it has only one pair and is not a rhombus.It is an impossible figure.

A square. Parallelogram * * * * * No. It is a rhombus and a square is a special case of a rhombus. A parallelogram does not have four congruent sides, but two pairs of sides that are congruent to one another.
