No, not every parallelogram has angles of 90 degrees. A parallelogram is defined as a quadrilateral with opposite sides that are parallel, and while it can have right angles (making it a rectangle), it can also have angles that are acute or obtuse. The only requirement is that opposite angles are equal and adjacent angles are supplementary. Thus, while rectangles and squares are special types of parallelograms with right angles, most parallelograms do not have all angles at 90 degrees.
What else can I help you with?
Does a parallelogram have a rotation symmetry?
Yes, 180 degrees. In the degenerate case that the parallelogram is a square, then 90 degrees.
How many angles of a rectangles must be 90 degrees to make surte its a parallelogram?
If it is a rectangle, then all its angles are 90 degrees and it is a parallelogram!
How many angles must measure 90 degrees in a parallelogram?
It is not a requirement that any of the angles are right angles (90 degrees), to qualify as a parallelogram.
Can a parallelogram have 90 degrees angles?
Yes!
Is every rectangle parallelogram?
Yes, every rectangle is a parallelogram. Parallelograms are defined as a shape with opposite, but parallel sides. A rectangle is defined as a shape with 90 degree angles, 2 sets of parallel sides, and the opposite sides must be equal in length. Because the sides of any rectangle are parallel, any qualified rectangle is a parallelogram.

Yes, 180 degrees. In the degenerate case that the parallelogram is a square, then 90 degrees.

Can a parallelogram have 90 degrees angles?
Yes!
Is each interior angle of a quadrilateral always 90 degrees?
No. in a rhombus the angles are not 90 degrees. also in a parallelogram they are not 90 degrees
Are all angles of a parallelogram equal to 90 degrees?
No, only in a square (regular parallelogram).The opposite angles are EQUAL in a parallelogram, and the adjacent angles are SUPPLEMENTARY(they equal 180 degrees).So if any angle in a parallelogram is a right angle, they all are. Otherwise, there are no right angles.The angles of a parallelogram will average 90 degrees, as there are 360 degrees in any quadrilateral, (360/4 - 90) and 180 degrees in two adjacent non-equal angles (180/2 = 90).
What is a word that have no angles of 90 degrees?
A rhombus or a parallelogram
Is every rectangle parallelogram?
Yes, every rectangle is a parallelogram. Parallelograms are defined as a shape with opposite, but parallel sides. A rectangle is defined as a shape with 90 degree angles, 2 sets of parallel sides, and the opposite sides must be equal in length. Because the sides of any rectangle are parallel, any qualified rectangle is a parallelogram.
Does a rectangle square rhombus trapezium kite parallelogram diagonals intersect each other at 90 degrees Celsius?
a square,rhombus,parallelogram does intersect at 90 degrees but a rectangle does not intersect at 90 degrees and im not sur about trapezuim and kite:)
Is it posibale for a parallelogram to ever be a rectangle why or why not?
No, but it is possible for a parallelogram to be a rectangle - when the angles are all 90 degrees.
What do you call a parallelogram with internal angles of 90 degrees?
A rectangle.
What is a parallelogram with equal angles?
A rectangle has 4 interior equal angles of 90 degrees each and it is technically a parallelogram.
