• Acute triangulation
• pentagon
• double pentagon
• Helly's theorem

An acute triangulation is a triangulation whose triangles have all their angles less than In this paper we prove that i) every planar pentagon can be triangulated into at most 54 acute triangles, and ii) every double pentagon can be triangulated into at most 76 acute triangles.
