field theory - Prove $80^ {\circ}$ is not a constructible angle . . . A usual proof that trisection is impossible with straight-edge and compasses does it by showing that $20^\circ$ is not constructible (but since $60^\circ$ is constructible, trisection is not possible) So if we construct $80^\circ$, bisecting twice would give us $20^\circ$, contradiction
symbols - Circle above a letter - TeX - LaTeX Stack Exchange I could write a circle above the letter but it seems far a little bit Is there a way to get it down a little bit, because I really use it a lot and it takes a lot of space Here is a sample of the
