It is sometimes true that a parallelogram has a right angle.
A parallelogram with a right angle is a rectangle.
A parralleogram is a quadrilater so a shape with 4 sides that has equal opposites
Except for the special case of a rectangle, a parallelogram must have two acute angles.

If the lengths of adjacent sides are s and t, and the angle between then is x, thenarea = s*t*sin(x).
If the adjacent sides are of lengths x and y units and the angle between then is t, then,Area = a*b*sin(t).
If a parallelogram has adjacent sides of length a and b and the angle between then is x, thenarea = a*b*sin(x).
If a parallelogram has adjacent sides of length a and b and the angle between then is x, thenarea = a*b*sin(x).
