AB - We consider triangulations formed by triangular elements. For the standard linear interpolation operator $\pi __h$ we prove the interpolation order to be $\left\Vert v-{\pi __h} v\right\Vert _{1,p}\le Ch\left|v\right|_{2,p}$ for $p>1$ provided the corresponding family of triangulations is only semiregular. In such a case the well-known Zlámal’s condition upon the minimum angle need not be satisfied.
