This result has been derived by a fundamental equivalence, for which we will need the following definitions: Let S = {[x1, y1], [x2, y2],..., [xn, yn]} be a set of intervals and let 0 <c ≤ 1.0 denote the same relative tolerance for all intervals. Let T(S) denote a set of triangles Δi = {Ai, Bi, Ci}, Ai, Bi, Ci ∈ (ℕ × ℕ) with the following coordinates:
