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 shape is a square but not a parelellogram?
No shape is a square but not a parallelogram as all squares are parallelograms: All parallelograms have opposite sides parallel and of equal length, and opposite angles are equal. All squares have opposite sides that are parallel and of equal length, and opposite angles are equal; thus all squares are parallelograms. However, all squares also have all angles equal to 90o and all four sides equal, but some parallelograms have angles not all 90o and/or not all four sides of equal length; thus not all parallelograms are squares.
A quadrilateral whose opposite sides are parallel and opposite angles are congruent and that has four congruent sides is a?
this would be a rhombus. rhombuses are parallelograms (four-sided shapes with opposite sides parallel) that have all equal side lengths. squares are included as rhombuses.
Do all quadrilaterals have opposite sides parallel?
No, only trapeziums (1 pair), parallelograms and squares (both pairs)
What quadrilateral had opposite sides parallel and all sides congruent?
A square's opposite sides are parallel and all the sides are congruent.
Do all squares have two pairs of opposite sides that are parallel?
Yes.

What is a plain figure in which all of the angles are right angles opposite sides are parallel and opposite sides are equal?
rectangles squares

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.

What are the types of parallelogram?
A parallelogram has opposite sides parallel and equal in length, and opposite angles are equal. Squares, rectangles and rhombuses are all parallelograms.
If all rectangles are parallelograms are all squares parallelograms?
Yes. Squares are just complex rectangles, as the definition of a rectangle is that it has four right angles with opposite sides being parallel.
What makes a rectangle and a squarea llike and what makes them different?
Rectangles and squares are alike in that both pairs of their opposite sides are parallel and their inner corners are all 90-degree angles; they are different in that squares have equal lengths on all sides, and only rectangles' opposite sides are the same lengths.
Do all squares have two parallel sides?
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).
