The term "reentering polygon" refers to a specific type of shape in geometry. Let's break it down to help you understand it better.

Definition:
  • Reentering Polygon (noun): A polygon that has one or more reentrant angles. A reentrant angle is an angle that points inward, meaning that it goes back inside the shape instead of sticking out.
Usage Instructions:
  • You can use the term "reentering polygon" when discussing shapes in geometry, especially when describing specific characteristics of polygons.
Example:
  • A classic example of a reentering polygon is a star shape. The points of the star bend inward, creating reentrant angles.
Advanced Usage:
  • In more advanced discussions, you might come across reentering polygons when studying topics like computer graphics, architecture, or advanced mathematics, where understanding the shape's properties is crucial.
Word Variants:
  • There are no common variants of "reentering polygon" itself, but you may encounter related terms like "polygon" and "reentrant angle."
Different Meaning:
  • In general, the word "reenter" means to enter again. However, in geometry, it specifically refers to the angles of the polygon.
Synonyms:
  • While there are no direct synonyms for "reentering polygon," you can describe it using terms like "concave polygon" or "non-convex polygon," which refers to polygons that have indentations (like a reentrant angle).
Related Terms:
  • Polygon: A closed shape with straight sides.
  • Concave: A shape that curves inward.
  • Convex: A shape that curves outward, without any indentations.
Idioms and Phrasal Verbs:
  • There are no idioms or phrasal verbs directly related to "reentering polygon," as it is quite a technical term used mainly in mathematical contexts.
Summary:

A reentering polygon is a polygon that has at least one angle that points inward. It's important in geometry, especially when studying different types of shapes and their properties.

Noun
  1. a polygon with one or more reentrant angles
