Are all trapezoids parellelograms?
No
Are all rectangles parellelograms?
Yes.
Are all quadrilaterals parellelograms?
No, a trapezoid is not a parallelogram.
Why are all rhombuses squares?
All rhombuses are NOT squares.
Are all squares parellelograms?
A square is parellelogram because all the sides are equal.
Is a square a rombus?
yes all squares are rhombuses but not all rhombuses are squares
Are all parellelograms special kinds of squares?
No. But squares are a special kind of parallelogram.
Are parallelograms rhombuses?
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.
Are all square is rhombuses?
Yes Every square is a rhombus, but not all rhombuses are squares.
Can a rhombus be a parallelogram?
All rhombuses are paralleleograms. Rhombuses are parallelograms in which all four sides are the same length (and the opposite angles are congruent). Squares are rhombuses in which all four angles are right.
Are all rhombuses also rectangles?
No. Rhombuses that are also rectangles are called squares. Rhombuses are parallelograms with 4 equal sides, while rectangles are parallelograms where all the angles are right.
Are there any trapezoids that are also rhombuses?
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)
