Galois theory characterizes classical problems like angle trisection and doubling the cube as impossible using only compass and straightedge because their underlying Galois groups are non-solvable.
Conditions: Classical geometric problems; Restricted to compass and straightedge constructions; Relies on the concept of solvable groups
