Abstract: The Lagrange interpolation of   Πk(R2) space is studied.The method of constructing the properly posed set of nodes for Lagrange interpolation in the  Πk(R2)space is given,and this generalizes the main method of constructing the properly posed set of nodes for Lagrange interpolation in the  Πk(R2) space which was acquired by Ward Cheney and Will Light in “The tutorial of approximation theory”.Thus a general conclusion is obtained.

Key words: Πk(R2) , space;properly posed set of nodes;multivariate polynomial;Lagrange interpolation;multivariate interpolation
