When one deals with symbolic entities, it often happens that an assertionĬannot be guaranteed.
The intersection of entities that do intersect may result in an emptyįuture Work # Truth Setting Expressions # Point.is_collinear) may not actually do so. Properly and hence some things that should return True (e.g., Since SymPy is still in its infancy some things may not simplify With complex polygons (overlapping sides). Hence, expect potential problems if dealing Positive value be sure to use the abs function.Īlthough Polygon can refer to any type of polygon, the code has been Negative value, depending on whether or not the points are orientedĬounter-clockwise or clockwise, respectively. The area property of Polygon and Triangle may return a positive or “Pappus’s Hexagon Theorem” Wikipedia, the Free Encyclopedia.

The following Python session gives one an idea of how to work with some of the Values please see the list of classes at the end of this document. These entities, but several global methods exist:įor a full API listing and an explanation of the methods and their return Most of the work one will do will be through the properties and methods of The following entities are currently available in the geometry module: It is possible to also use symbolic representations. The primary use case of the module involves entities with numerical values, but This could include asking the area of an ellipse, checking forĬollinearity of a set of points, or finding the intersection between two lines. The geometry module for SymPy allows one to create two-dimensional geometricalĮntities, such as lines and circles, and query for information about theseĮntities.
