theorem
A deductively valid argument is if the premises are true then the conclusion is certainly true, not possibly true. The definition does not say that the conclusion is true.

True. Euclid showed that more complex geometry could be described and proven deductively from a few simple principles.

Yes, deductively sound arguments are deductively valid. A deductively valid argument is one where it is impossible for the premises to be true and the conclusion false. If the argument is deductively valid and the premises are also true, then the argument is sound.

A theorem is proven. An example is The "Pythagoras Theorem" that proved that for a right angled triangle a2 + b2 = c2
