Тезаурус:

1. Before he was 19, Gauss had constructed, by straightedge and compass, a regular 17-gon, the first new constructible regular polygon for 2000 years, and in 1799 he gave the first satisfactory proof (where Newton, Euler and Lagrange had failed) of the fundamental theorem of algebra (4.8.1).
2. But what made him choose to devote himself to mathematics was his finding in 1795 of the criterion for a regular n-gon to be constructible using only compass and straightedge.
