The geometric concepts are presented well, but the language is not clear. The topic requires not just an explanation of points, rays, lines, segments, circles, angles and other elements of planimetry, it also demands an authoritative command of the language to define the terms, theorems, and corollaries. I doubt that the authority of language was lost in the translation from Russian. This book is disappointing in the way it discusses the subject with the apparent assumption that the reader understands terms and concepts perfectly even though they have only been poorly explained in the author's words. It's like reading a badly written product manual. One can very well learn to operate the product, but it's so much more pleasant when the instructions are more perfectly lucid. Only with such definitive language could a book on geometry take the place of authority this one appears to have been given by others.
