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)
When combining rhombuses, each rhombus has 4 sides. So, if you combine 5 rhombuses, you will have a total of 5 x 4 = 20 sides. Each rhombus has 4 equal sides, so when they are combined, the total number of sides will be a multiple of 4.
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.
