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
What is a parallelogram with all same angles and all same sides?
A square.

The name of a parallelogram in which all angles are the same measure is a?
rectangle.

Is a parallelogram a irregular polygon?
Yes, a parallelogram is an irregular polygon because its sides and angles are not all the same. For a shape to be a regular polygon it must be equangular (all angles are the same) and equilateral (all sides have the same length).
How do you find missing angle of a parallelogram?
Being a quadrilateral, the sum of all four angles is 360o.Opposite angles of a parallelogram are equal.Adjacent angles of a parallelogram are supplementary, that is add to 180o.Given one angle of a parallelogram, the other 3 angles can be calculated:the opposite angle is the same;the other two angles are the same as each other and are 180o - the_given_angle
A rectangle with 4 right angles and all sides the same?
parallelogram
What do you call a parallelogram that has all right angles and has all sides same length?
A square.
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
If each side of a quadrilateral is congruent to its opposite side then the quadrilateral is a rectangel?
Not necessarily; it is a parallelogram - a rectangle is a parallelogram in which all angles are 90o. It could also be a rhombus - a rhombus is a parallelogram with all lengths the same; a square is a rhombus in which all angles are 90o.
