:D I think that it is a rhombus cause a rhombus has four congruent sides but may not be a square or a rectangle.
its a rectangle
Not necessarily.
A parallelogram cannot have only two congruent sides, nor only two congruent angles.
A rhombus (4 congruent sides, diagonals perpendicular)that is not also a square (no right angles), andis also a parallelogram (opposite sides parallel and congruent, opposite angles congruent). It is also a quadrilateral, which has 4 sides.
No, not necessarily. A parallelogram can have all sides equal, but still not be a square.
Yes, the opposite sides of a parallelogram are congruent.
No. If you made a parallelogram with congruent sides it wouldn't necessarily have congruent angles. A square has to have congruent angles as well as congruent sides.
Not necessarily.
A parallelogram with no right angles and four congruent sides is a Rhombus.
A parallelogram cannot have only two congruent sides, nor only two congruent angles.
A square
A parallelogram which has all congruent sides and angles is a square.
All angles of a parallelogram are not necessarily congruent. A parallelogram means that the opposite sides run in straight lines that don't intersect. An example is a rectangle or square. Length of sides DO NOT determine if opposite angles are congruent. As long as opposite sides do not intersect each other at any point (if you continue to draw the lines), then the angles diagonal from each other are the same.
Yes. A parallelogram has congruent opposite sides as well as congruent opposite angles.
A rhombus is a parallelogram with all four sides congruent to each other with no right angles. A square is a parallelogram with four congruent sides and four right angles.
No. In a regular polygon, all sides are congruent, and all angles are congruent. A parallelogram doesn't satisfy either of these conditions.No. In a regular polygon, all sides are congruent, and all angles are congruent.

A square is the parallelogram that has all sides congruent. A square also has four angles that are all right angles.
A trapezoid.
