Gallery: UML Parsing Analysis demonstration: Wikipedia Shapes (from 2009)

This content is for DEMONSTRATION

The challenge:

Draw a class diagram for the shapes triangle, square, circle, and ellipse.

Sounds so easy, right ? Four little shapes. Now that can't be too hard. Well it's hard enough that one does well to engage the help of the Wikipedia geometry and shape articles ! Let's use UML™ Parsing Analysis to build up a solution sentence-by-sentence, employing Dr Darren's «wrapper» Components trick (in this case in MagicDraw™ UML).

Note that even though this is only and analysis example, Java-friendly Thing/Thing_ Interface/Class ("default implementor") style will be used (rather than say permitting Associations from Interfaces, or using just entity Classes throughout).

Start here to work through the trail (or use the unordered gallery at the bottom of the page):

Convex quadrilaterals are further classified as follows:

In mathematics, a locus (Latin for place, plural loci) is a collection of points which share a property

A circle is the locus of points from which the distance to the center is a given value, the radius.

In mathematics, a conic section (or just conic) is a curve obtained by intersecting a cone (more precisely, a circular conical surface) with a plane.

'Shape is all the geometrical information that remains when location, scale and rotational effects are filtered out from an object.'	These segments are called its edges or sides, and the points where two edges meet are the polygon's vertices or corners.	A shape whose points belong all [in] the same plane is called a plane figure..jpg
A diagonal can refer to a line joining two nonconsecutive vertices of a polygon or polyhedron	Rhombus or rhomb: all four sides are of equal length.	In geometry a polygon .. is traditionally a plane figure that is bounded by a closed path or circuit, composed of a finite sequence of straight line segments (i.e., by a closed polygonal chain)
A regular polygon is a polygon which is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).	Trapezium .. two opposite sides are parallel.	Square (regular quadrilateral)_ all four sides are of equal length (equilateral), and all four angles are right angles
In mathematics, a locus (Latin for place, plural loci) is a collection of points which share a property	An equilateral polygon is a polygon which has all sides of the same length.	A triangle is one of the basic shapes of geometry_ a polygon with three corners or vertices and three sides or edges which are line segments
In mathematics, a conic section (or just conic) is a curve obtained by intersecting a cone (more precisely, a circular conical surface) with a plane.	A quadrilateral is a polygon with four 'sides' or edges and four vertices or corners.	Convex quadrilaterals are further classified as follows:
A circle is the locus of points from which the distance to the center is a given value, the radius.	In the Cartesian coordinate system, the graph of a quadratic equation in two variables is always a conic section, and all conic sections arise in this way	Standpoint: A circle is a distinct conic
Standpoint: A circle is a kind of ellipse
