Thanks immensely for your inputs on DG. (I'm getting so comfortable with it I'm calling it by its nickname!) I'm going to share your insights with my students. They still are not really convinced that they can do this all on their own .... sans lectures. So far the work/investigative groups have been developing conjectures (SSS,SAS and ASA) that we already "proofed" in the "2-column era" before we switched to DG last November. Now they're saying "Is that what those proofs were all about?" Again, thanks. I'm truly grateful.
