We introduce a kind of converse of Pompeiu’s theorem. Fix an equilateral triangle, then for any trianglethere is a unique pointPinside the circumcircleofsuch that a triangle with edge lengths, andis similar to. It follows that an open disc insidecan be considered as a moduli space of similarity classes of triangles. We show that it is essentially equivalent to another moduli space based on a shape function of triangles which has been used in preceding studies.
