Hilbert’s axiom’s changed euclid’s geometry by
1 disproving euclid’s postulates
2 utilizing 3-dimensional geometry instead of 2-dimensional geometry
3 describing the relationships of shapes
4 identifying and explaining the concept of undefined terms

I think the correct answer from the choices listed above is option 2. Hilbert’s axiom’s changed Euclid’s geometry by  utilizing 3-dimensional geometry instead of 2-dimensional geometry. Hilbert is also known for his axiomatisation of the Euclidean geometry with his set of 20 axioms.
