The group transformation theoretic approach is applied to present
an analytic study of the temperature distribution in a triangular
plate, , placed in the field of heat flux, along one
boundary, in a form of polynomial functions of any degree . The Laplace's equation has been reduced to second-order
linear ordinary differential equation with an appropriate
boundary conditions. Exact solution has been obtained for general
shape of and different boundary conditions.
