A square is a four-sided polygon with two congruent parallel sides.
A rectangle is a quadrilateral with opposite sides parallel and congruent and four right angles. If all four sides are congruent, it is a square.
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
A diamond is actually an informal term for a rhombus, which has four equal sides(congruent is not used to refer to equal sides), with the opposite sides being parallel to one another.So a "diamond" has four equal sides and two pairs of parallel sides.
Rhombus has four congruent sides.Opposite sides are parallel. congruent is same.
Yes (the sides are parallel in pairs - two of the sides are parallel, and the other two are parallel among themselves).
There are: Squares, which have all four sides parallel and congruent, all four angles are right and congruent, the diagonals bisect each other and are congruent. Trapezoids, which have two of their sides parallel Rhombus, which have all sides congruent, diagonals bisect, and opposite angles are congruent Parallelograms, which have opposite sides congruent and parallel, diagonals bisect Rectangle, which is a square but one pair of opposite sides aren't congruent.
It is a square or a rhombus
