The Drummond Geometry Forum

Thanks for providing me with a list of lines and respective order to be learned in regards to Lesson 2. Out of curiosity, why did you not mention
or list the 6/7, 6/6 or 1-1? Perhaps I misunderstood you. Please clarify.

6/7 and 6/6 are perhaps not as frequently occurring... However the 1-1's are definitely on the list of frequent items...

But all are ultimately useful. It was just a suggestion about which to learn first.
