Parallelogram

length equal adjacent perpendicular

A parallelogram is a plane figure of four sides whose opposite sides are parallel. A rhombus is a parallelogram with all four sides of equal length; a rectangle is a parallelogram whose adjacent sides are perpendicular; and a square is a parallelogram whose adjacent sides are both perpendicular and equal in length.

The area of a parallelogram is equal to the length of its base times the length of its altitude.
