Resources for solving Euclidean geometry problems using symmetries

Question

I know a number of books that treat geometry from the viewpoint of transformations/symmetries. However, very few of them actually teach someone to solve Euclidean geometry problems using said symmetries.

Are there any books who fill this gap? Here is an example of problem solved using symmetry.

Answer 1

See Geometric Transformations I, II, III, IV by Yaglom.
