The figure being described is generally called a "kite." In fact, it looks like a kite (that a child would fly). It has 2 pairs of congruent sides (let's say sides AB and BC are congruent, and sides CD and DA are congruent). It is not a parallelogram because the opposite sides are not parallel.
For an exact definition of kite, I give you what Prof. Moise uses: A kite is a quadrilateral in which exactly one diagonal is the perpendicular bisector of the other diagonal. (If both diagonals were perpendicular bisectors of each other, the figure would be a rhombus, and therefore a parallelogram. To add to the definitional confusion, Prof. Conway would, in fact, call all rhombuses kites. Most writers use the definition set forth by Prof. Moise, however.)
