An oval (from Latin ovum 'egg') is a closed curve in a plane which resembles the outline of an egg. The term is not very specific, but in some areas ( projective geometry , technical drawing , etc.) it is given a more precise definition, which may include either one or two axes of symmetry of an ellipse .

Qvist's theorem [3] [4]. Let Ω be an oval in a finite projective plane of order n. (a) If n is odd, every point P ∉ Ω is incident with 0 or 2 tangents. (b) If n is even, there exists a point N, the nucleus or knot, such that, the set of tangents to oval Ω is the pencil of all lines through N.
The OVAL Interpreter is a freely available reference implementation created to show how data can be collected from a computer for testing based on a set of OVAL Definitions and then evaluated to determine the results of each definition. The OVAL Interpreter demonstrates the usability of OVAL Definitions, and can be used by definition writers to ...
Trivia questions for kids can be brain-bending fun for the whole family. Asking kids thought-provoking questions is a great way to engage their critical-thinking skills, according to Laura Linn ...
A worksheet, in the word's original meaning, is a sheet of paper on which one performs work. They come in many forms, most commonly associated with children's school work assignments, tax forms, and accounting or other business environments. Software is increasingly taking over the paper-based worksheet.
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]
The simplest example of a coordinate system is the identification of points on a line with real numbers using the number line.In this system, an arbitrary point O (the origin) is chosen on a given line.
