"error in pythagorean theorem proof %236"

In Proof #6, should it start, "We start with original RIGHT triangle ABC..." and also, when listing the similar triangles in the second sentence, it should read, "triangles ABC, DBA, and DAC are similar."

I would not call it an error, no. But the way you propose may suggest to the reader a particular attention to detail on the part of the author. Which I think will cause no harm and may even endear the author with the readers.

With sincerest thanks,
