In particular, these are common traits of ovals: they are differentiable (smooth-looking), simple (not self-intersecting), convex, closed, plane curves; their shape does not depart much from that of an ellipse, and an oval would generally have an axis of symmetry, but this is not required.

Det kurvorna har gemensamt är: de är differentierbara, enkla (skär inte sig själva), konvexa, slutna, plana kurvor. deras form avviker inte alltför mycket från ellipsens det finns åtminstone en symmetriaxel.
