This is a list of two-dimensional geometric shapes in Euclidean and other geometries. For mathematical objects in more dimensions, see list of mathematical shapes. For a broader scope, see list of shapes.
Macroovalocytes are enlarged, oval-shaped erythrocytes (red blood cells). They are not seen in healthy blood, and are most commonly seen in megaloblastic anemia. [1] In most instances, the macroovalocyte morphology is due to megaloblastic erythropoiesis (Vitamin B-12 or folate deficiency) but may be seen with dyserythropoiesis.
A two-dimensional orthographic projection at the left with a three-dimensional one at the right depicting a capsule. A capsule (from Latin capsula, "small box or chest"), or stadium of revolution, is a basic three-dimensional geometric shape consisting of a cylinder with hemispherical ends. [1]
Additionally, if a spherical wavefront is refracted through a spherical lens, or reflected from a concave spherical surface, the refracted or reflected wavefront takes on the shape of a Cartesian oval. The caustic formed by spherical aberration in this case may therefore be described as the evolute of a Cartesian oval. [5]
The shape is based on a stadium, a place used for athletics and horse racing tracks. A stadium may be constructed as the Minkowski sum of a disk and a line segment. [6] Alternatively, it is the neighborhood of points within a given distance from a line segment. A stadium is a type of oval.
The term oval when used to describe curves in geometry is not well-defined, except in the context of projective geometry. Many distinct curves are commonly called ovals or are said to have an "oval shape". Generally, to be called an oval, a plane curve should resemble the outline of an egg or an ellipse. In particular, these are common traits ...
A Cartesian oval is the set of points for each of which the weighted sum of the distances to two given foci is constant. If the weights are equal, the special case of an ellipse results. A Cassini oval is the set of points for each of which the product of the distances to two given foci is constant.
A tri-oval shape. A tri-oval is a shape which derives its name from the two other shapes it most resembles, a triangle and an oval. Rather than meeting at sharp, definable angles as the sides of a triangle do, in a tri-oval these angles are instead rounded into smooth curves. [1] While an oval has four turns, a tri-oval has six.
