A square , a rectangle , a rhombus , in fact all the parallelograms have two parallel sides . Also a trapezium also has two parallel sides , which means one pair of parallel sides . The parallelograms have four parallel sides.
By definition, all squares are parallelograms. Not all parallelograms, however, are squares. All rectangles and rhombuses are also parallelograms.
No, they cannot be. All parallelograms must have two pairs of parallel sides whereas a trapezium can have only one such pair.
parallelograms.
All trapezoids are also parallelograms.
rectangle, rhombus, square, trapezoid, kite, parallelogram ~note: there are also irregular quadrilaterals that consist of four sides ~ALSO: squares, rectangles, and rhombuses are all parallelograms * * * * * A chevron is also a quadrilateral. A concave one, but a quadrilateral all the same.
A rhombus is parallelogram with 4 equal sides. A trapezoid (trapezium) has only one pair of parallel sides so it is not a parallelogram. So it is not a rhombus! (Remember squares, rectangles and rhombuses are all parallelograms, but trapezoids are NOT). Dr. Chuck
Trapezoid. The rectangle, square, and rhombus are all parallelograms. The Trapezoid is a solid: a prism of trapezium cross-section.
Parallelograms are squares is sometimes true. Squares are parallelograms is always true. Rhomboids are parallelograms is also always true. So not all parallelograms are squares but some are.
Answer: A parallelogram is a quadrilateral with both pairs of opposite sides parallel. If a quadrilateral is a parallelogram, the 2 pairs of opposite sides are congruent. If a quadrilateral is a parallelogram, the 2 pairs of opposite angles are congruent. Answer: No. On the other hand, all parallelograms are quadrilaterals.
All squares are parallelograms, but all parallelograms are not squares.
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.
