Abstract.The astrid is a family of graphs in the Cartesian plane
that frequently appears as an enrichment activity in the
elementary setting. Many variations of the astrid exist, but the
most common is a finite collection of straight line segments. The
exploration of the graph theoretic properties of this version of
the astrid will be the main focus of this paper.
