• Interpolation error
• Finite element methods
• The maximum angle condition
• The circumradius condition

In this paper the error of polynomial interpolation of degree 1 on triangles is considered. The circumradius condition, which is more general than the maximum angle condition, is explained and proved by the technique given by Babuska-Aziz.
