I would like to give some feedback about ...
The definition for the "similar triangles" seems, wrong: the "reflection" assertion and following "scaling and reflection" have to be False.
1) ∠A = ∠X, ∠B = ∠Y and ∠C = ∠Z
2) AB/XY = BC/YZ = AC/XZ
∠A, ∠B, ∠C are the angles of one triangle
∠X, ∠Y, ∠Z are the angles of another triangle
AB, BC, AC are the sides of one triangle
XY, YZ, XZ are the sides of another triangle
