I got this book yesterday in the mail. It's a good book but there seems to be an error on page 27 regarding fig 26 on page 26. The author states that angle TCP and TPD are the same and I don't see it. Does anybody here have the same book? Thanks, Eric

I think the nomenclature may be wrong, but the angles are the same. /mark

Hi- think the problem is that the drawing is out of scale. Move point c down a couple of inches and it makes sense.Or, locate point c by dropping a perpendicular from line TP from point T until it intersects line PC and see how it looks. Note that angleTPD is the compliment of angle TCP and so is angle PCT. Therefore they must be equal.
