Oval
An oval is a curve resembling a squashed Circle but, unlike the Ellipse, without a precise mathematicaldefinition. The word oval derived from the Latin word ``ovus'' for egg. Unlike ellipses, ovals sometimes have only asingle axis of reflection symmetry (instead of two).
Ovals can be constructed with a Compass by joining together arcs of different radii such that the centers of thearcs lie on a line passing through the join point (Dixon 1991). Albrecht Dürer used this method to design a Romanletter font.
