How many right angles does a parallelogram?
A parallelogram doesn't need any right angles in order to be a parallelogram.If it has any, then it's a special kind of parallelogram, called a "rectangle".Note:The way the properties of a parallelogram work out,if it has one right angle, then it has four of them.

Why is square parallelogram?
A square is a type of parallelogram because it has all the properties of a parallelogram. Specifically, a square has opposite sides that are parallel and equal in length, and opposite angles that are equal. However, a square also has additional properties that make it unique, such as all sides being equal in length and all angles being right angles.
