Reentrant Polygon (Noun)
Meaning
A polygon with one or more reentrant angles.
Classification
Nouns denoting two and three dimensional shapes.
Examples
- A reentrant polygon has interior angles greater than 180 degrees and its edges do not intersect except at the vertices.
- The diagram depicts a reentrant polygon with one exterior angle measuring less than 90 degrees.
- When using a Geographic Information System, you should ensure that polygons with reentrant angles are handled correctly.
- Computational geometry often encounters problems related to processing and triangulating reentrant polygons efficiently.
- Convex hull algorithms usually cannot directly process reentrant polygons due to the interior concavity of such shapes.
