If you mean a parallelogram then it is a 4 sided quadrilateral with opposite parallel sides
no a its a scalene accutally becuz a sqare never going to be parrel so its not parrelogram!
Base x height
No they do not HAVE to be the same but they can be the same
No, opposite sides are equal.
trapezium,rhombus and parrelogram
You add up the lengths of the 4 sides.
They are parallel sides that are equal in length
The formula for a parrelogram is area=base*height. In this case it will equal to 360 degrees:)
No, all parallelograms are quadrangles or quadrilaterals which have 4 sides. Hexagons have 6 sides.
