All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular.
The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).

Do all squares have two pairs of parallel sides?
Yes the sides are all the same as well too.
What quadrilaterals have two parallel sides'?
Squares, rectangles, parallelograms and rhombuses have two parallel sides. The other two are also parallel. A trapezium has only two parallel sides.
Why can all squares be classified as parallelograms but not all parallelograms can be classified as squares?
A parallelogram is a four-sided figure with opposite sides parallel. Squares and rectangles are two examples of parallelograms. A square is a four-sided figure that has four equal sides, and opposite sides are parallel.
What is the main difference between squares and trapezoids?
The main difference between squares and trapezoids is that, while the length all four sides of a square are equal, trapezoids have two sides with equal length and two sides of different length. Also, the opposite pairs of sides in a square are parallel, while only one pair of sides in a trapezoid is parallel.
What other name is for a rectangle?
Rectangles are quadrangles, polygons with four sides. A rectangle is a quadrangle with two long sides and two short sides, and the long sides and short sides are parallel to each other. They are parallelograms, in which opposite sides are parallel. Note: All squares are also rectangles.
Two quadrilaterals that have two pairs of parallel sides each In addition all four of the sides are congruent in both shapes?
The two quadrilaterals are squares.
What two quadrilaterals have opposite sides equal and parallel?
parallelograms and squares.
What shape with 4 sides has 2 pairs of parallel sides?
Quadrilaterals with two sets of parallel sides are parallelograms. Parallograms include squares, rectangles, and rhombi (rhombuses).
Can you call a 4 sided shape a parallellogram?
Only if 2 sides are parallel with each other, and the other two sides are also parallel with each other. All squares are rectangles. All rectangles are parallelograms. All parallelograms are 4 sided. But not all 4-sided are parallelograms, not all parallelograms are rectangles, and not all rectangles are squares.
Are some parallelogram a square?
All squares are parallelograms. The definition of parallelogram is a quadrilateral with two sets of parallel sides. A square is a quadrilateral with two sets of parallel lines, so it is also a parallelogram
Do parallelograms have to be squares?
No.Parallelograms have two pairs of parallel opposite sides; they do not have to be the same length.The opposite angles of a Parallelogram are equal; they do not have to be 90oA square is required to have all sides equal (opposite sites will be parallel) and all angles 90o (opposite angles are the same)Thus all squares are parallelograms, but only some parallelograms are squares.A rhombus is a parallelogram which has all sides the same length.
Is a square a type of rectangle?
All squares are rectangles but not all rectangle are squares. The definition of a rectangle is a quadrilateral with two sets of parallel sides, and 4 right angles. A square meets both of these criteria, so it is categorized as a rectangle. But since a square has to have four even sides and a rectangle has to have two larger sides and two smaller sides it cannot be a square
How a parallelogram is a square?
Parallelogram is not a squareAnswerBy definition, all squares are parallelograms because opposing sides of any square are parallel to each other. However, not all parallelograms are square because their sides are not always an equal length, nor are the angles of any two adjacent sides always 90 degrees. Therefore, all squares are parallelograms, but not all parallelograms are squares.
Is every rectangle also a square?
Yes all squares meet the requirements of a rectangle. They are equiangular quadrilaterals (have 4 equal angles) and have two pairs of opposite parallel sides. Squares are a subset of all equilateral rectangles. Thus, all squares are rectangles, but only some rectangles are squares.Yes all squares are rectangles because they have four equal angles and two pairs of opposite parallel sides. Not all rectangles are squares however, because only some of them are equilateral.
Are all rectangles squares?
No. A square must be a rectangle, but a rectangle does not have to be a square.A square is a rectangle that has four sides of equal length.--A rectangle MUST have the following:Four sidesFour angles that are right angles (90 degrees), so that the total is 360 degrees.Two pairs of parallel sidesTwo pairs of equal sidesA square MUST have the following:Four sides (All must be the same length)Four angles(Must all be 90 degrees)Two pairs of parallel sidesBecause of that not all rectangles are squares but all squares are rectangles.---Rectangles are parallelograms with all right angles, and opposite sides are congruent. Squares are parallelograms with all right angles, and ALL sides congruent. Therefore, all squares are rectangles, but not all rectangles are squares.False! squares have 4 equal sides and rectangles don't they only have 2 equal sides. Some rectangles are squares, but not all of them. On the other hand, all squares are rectangles.
What type of quadrilateral has two pairs of parallel sides?
It would have to be a rhombus. A trapezoid ONLY has one pair of of parallel sides.Rectangles, squares and rhombuses are special cases of parallelograms:Rectangle = a parallelogram with two pairs of equal sides and all angles 90oSquare = a parallelogram with all sides equal in length and all angles 90oRhombus = a parallelogram with all sides equal in length, but all angles not (necessarily) 90o
What shape has 2 parallel sides?
A four sided shape with 2 parallel sides is called a trapezium. A four sided shape with 2 pairs of parallel sides is called a Parallelogram; This includes squares, rectangles and rhombi. If you want to find more about this you can check on google.
