Generally, there are no right angles in a parallelogram, but rectangles and squares can be seen as special parallelograms, as they have all the qualities needed to be classed as parallelograms, and in addition, they have four right angles.

What is a parellelogram with four congruent sides?
A parallelogram with equal sides is a rhombus. If the interior angles are right angles, it's a square.
Does a parallelogram have equal angles?
Yes, the opposite interior angles of a parellelogram are equal.
Why are the opposite angles in a parellelogram equal?
Because they are angles that are subtended by pairs of sides that are parallel to each other. There are several ways of proving the angles are equal.
How many angles and how many right angles in a square?
4 right angles, no other angles.
If all angles of a quadrilateral are congruent can the quadrilateral be a parellelogram?
well you can just talk a steamy poo on that homework your doing right know and go out and party cause this sight sucks any way
What is a parellelogram with 4 right angles?
It is a rectangle
What is a parellelogram with four right angles?
rectangle
Is a rectangle a parellelogram?
yes, a rectangle is a parallelogram with right angles.
How many obtuse angles are in a parellelogram?
Either 2 or 0
What is a parellelogram with four congruent sides?
A parallelogram with equal sides is a rhombus. If the interior angles are right angles, it's a square.
Are all the angles in a parellelogram equal?
All the angles in a parallelogram can be equal, but are not always.
Does a parallelogram have equal angles?
Yes, the opposite interior angles of a parellelogram are equal.
What figure is 2 dimensional with two pairs of parallel sides has no right angles and all sides are the same length?
A rhombus. More information... The no right angles is throwing me, but I will add this comment: A square A four-sided polygon having equal-length sides meeting at right angles. The sum of the angles of a square is 360 degrees. A Parellelogram is a four-sided polygon with two pairs of parallel sides. The sum of the angles of a parallelogram is 360 degrees. A Rhombus is a four-sided polygon having all four sides of equal length. The sum of the angles of a rhombus is 360 degrees. So, a Square is actually a Parellelogram and Rhombus as well; and it has 4 right angles. So... I am not sure that Parellelogram and Rhombus are what you were looking for,
A parellelogram with all sides and all angles congruent?
square.......
What do the interior angles of a parellelogram add up yo?
360 degrees
Why are the opposite angles in a parellelogram equal?
Because they are angles that are subtended by pairs of sides that are parallel to each other. There are several ways of proving the angles are equal.
You are quadrilateral with two parallel sides your opposite sides are congruent and you have acute and obtuse angles no right ones all four sides are not congruent what is the best name for you?
Parellelogram
