trapezoids have 4 sides, rhombuses have 4 sides
A rhombus has 4 sides.
A rhombus is a quadrilateral having 4 equal sides and no right angles
yes - all the rhombuses. By definition a trapezoid has two parallel sides, a rhombus also has two parallel sides - because both pairs of opposite sides are parallel. So all rhombuses are trapezoids (but not all trapezoids are rhombuses)
All rhombuses are parallelograms because to be a parallelogram you only have to have four sides and have opposite sides congruent.
Rhombuses always have 4 equal sides, trapezoids do not.
Some parallelograms are rhombuses, but all rhombuses are parallelograms. A parallelogram is a rhombus if and only if all of it's sides are the same length.
