I have two questions that I can't seem to find answers to (I've looked in
encyclopedias, libraries, etc.): 

1) What are the three constructions in Euclidian geometry that are 
impossible to achieve with only a compass and a straightedge?

2) What U.S. president found an independent proof of Pythagorean's theorem?

Any one know these?  I appreciate everyone's help!!
