In technical drawing, an oval is a figure that is constructed from two pairs of arcs, with two different radii (see image on the right). The arcs are joined at a point in which lines tangential to both joining arcs lie on the same line, thus making the joint smooth.

An oval shape is a smooth-looking closed shape and a curved geometrical figure. An oval shape has no straight sides. It has no corners or vertices like squares or rectangles. It has one flat curved face. In some cases of an oval shape, a line of symmetry can be observed.

An oval shape is a closed shape. It is a completely curved geometric figure. Thus, it has no straight lines or vertices. It looks like a stretched-out, elongated, or a squashed circle. The shape is very similar to the shape of an ellipse. However, they are not the same.

An oval shape is a closed shape. It is a plane curve geometrical figure. An oval has smooth-looking, simple, convex curves It has no straight lines or straight sides. A line of symmetry can be observed in some cases. An oval shape has no corners or vertices. Ovals have one flat and curved face which does not self-intersect at any point
