On Triangulations with Fixed Areas
TL;DR
This paper proves that the number of triangulations of a polygon into triangles with fixed face areas is finite, and demonstrates that an equidissection is algebraic when the polygon's vertices have algebraic coordinates.

We prove that the number of triangulations of a given polygon into triangles with fixed areas of faces is finite, and that an equidissection is algebraic as long as the vertices of the original polygon have algebraic coordinates.
