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.

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.
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.
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:)
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.
