Hi, I'm trying to understand why when a point belongs to a straight line the epura looks like this, in this case (A, B and C are the points) (R,T and (EF) are the lines)

 

Sorry eventual english mistakes :(post-128344-0-64196000-1492277525_thumb.

I'm not quite sure what you are asking because I don't know what epura means (graph?) and Google didn't provide a decent translation. Can you be more specific?

epura? Does it mean projection, transformation, or correction? Each of the diagrams has a line which is transformed in some way (A-->A' etc.) with a point in the middle of the line being the ones the OP is interested in
