angles diagnal from each other in a parallelogram are congruent for shape be parallelogram, all sides must be parallel
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.
are angels having not equal,zize shape and measurement
This is a parallelogram. The first requirement is 2 pairs of congruent sides where the congruent sides are not adjacent. This is like a rectangle (excluding a square) that has two pairs of congruent sides where the congruent sides are not adjacent. But the angles are not all congruent (as set in the question) which pushes the shape into the "next less regular" shape, the parallelogram. The angles will not all be congruent, but it will have 2 pairs of congruent angles. There is no way to avoid the 2 pairs of congruent angles because of the requirement that the shape must have 2 pairs of congruent sides (the first requirement).
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.
It is a rectangle
Square, rhombus possibly a parallelogram
A square
A parallelogram which has all congruent sides and angles is a square.
An equilateral parallelogram is a rhombus.If its angles happened to be right angles, then it would be a square.
Yes. A parallelogram has congruent opposite sides as well as congruent opposite angles.
