No. The parallellogram can have any four angles as long as its anglesum makes 360 and has the top and bottom, aswell as the left and right side the equivalent length.
What you are talking about is a rectangle (four corners, all angles the same = 90 degrees) or a square (the same as the rectanglem but with equivalent lengt on all sides).

Is a parallelogram always equiangular?
No. A parallelogram has two pairs of opposite angles that are equal but to be equiangular, all four angles must be the same. That is not necessarily the case in a parallelogram.
Are all the angles the same on a parallelogram?
No. There are lots of different types of parallelograms, which have varied angles.
Can a parallelogram be called a rectangle square or a rhombus?
A rectangle may be called a parallelogram but they are both 4 sided quadrilaterals. A parallelogram can be called a rectangle if all four angles are right angles (90 degrees). A parallelogram can be called a rhombus if all four sides are the same size. A parallelogram can be called a square if all four angles are right angles and all four sides are the same size
Is square a parallelogram with all sides equal?
Not unless all angles are also equal. A rhombus is a parallelogram with all sides equal. A rectangle is a parallelogram with all angles equal. A square is a rhombus with all angles equal which is a parallelogram with all sides equal and all angles equal.
What type of polygon has 4 congruent sides and not all angles are the same?
parallelogram
