A square is a rhombus by the modern definition of rhombus as a quadrilateral with four equal sides. An old definition of rhombus added the clause that it is not a square.
A rhombus is always a parallelogram, by definition.
A rhombus by definition has four sides, and a triangle has only three. So, a triangle is never a rhombus.
A rhombus, by definition, must be equilateral. Therefore, an isosceles rhombus cannot exist and so it cannot be a parallelogram.
Look at the definition of a rhombus. A square fulfills all parts of the definition.

Yes, by definition.
A rhombus, by definition, must be equilateral. Therefore, an isosceles rhombus cannot exist and so it cannot be a parallelogram.
A rhombus is NOT a regular polygon, since the angles need not be equal. A rhombus does have four equal sides, by definition.
Two parallel sides is part of the definition for a rhombus.
A parallelogram with four equal sides.
No, by definition a rhombus has all angles equal, but they are not right angles. A square is a type of rhombus with four right angles.

Errm, a Rhombus? A rhombus is defined as a quadrilateral with four equal sides and opposite sides parallel. A square also meets this definition of a Rhombus, but is a special Rhombus in that all the angles are 90°.
nothing fits the definition of rhombus and rectangles becauses the definition for rectangle is : a plane figure with four straight sides and FOUR RIGHT ANGLESbut the definition of rhombus is...a parallelogram with ,OPPOSITE EQUAL ACUTE ANGLES and OPPOSITE EQUAL OBTUSE ANGLES, and four equal sides.
