Abstract 

The construction of a new triangle by erecting similar ears on the sides of a given triangle (as in Napoleon's theorem) can be considered as the convolution of the initial triangle with another triangle. We use the discrete Fourier of such convolution filters and their iterates. Our method leads to many old and new results in a very direct way.
