    Title: Geometric triangulations of a family of hyperbolic 3-braids

 Abstract: After constructing topological triangulations of an
 infinite family of pretzel links, I will argue that the constructed
 triangulations meet a stronger condition: They are actually geometric.
 The proof follows a procedure outlined by Futer and Guéritaud and uses
 a theorem of Casson and Rivin.  Futer, Kalfagianni, and Purcell have
 shown (indirectly) that these links are hyperbolic. The new result here
 is a direct proof.
