Read § 4.7 118: 7, 10, 11 123: 1  4 and: Do you find fault with the solution written below of the following? Problem: Let A, B, and C be any points. If f is the unique translation for which f(A) = B, express f(C) as an affine combination of A, B, and C. Response: Regard A, B, and C as an affine basis for the plane containing these points. Then in the corresponding barycentric coordinates A = (1, 0, 0), B = (0, 1, 0), and C = (0, 0, 1). Since f is a translation and f(A) = B, in barycentric coordinates f must be translation by the vector (0, 1, 0)  (1, 0, 0) = (1, 1, 0). So f(C) must have barycentric coordinates (0, 0, 1) + (1, 1, 0) = (1, 1, 1). Therefore, f(C) = C + B  A.
