Proposition: 4.02: Inscribing in Circle Triangle Equiangular with Given Angles
Euclid's Formulation
To inscribe a triangle, equiangular with a given triangle, in a given circle.
* Let $ABC$ be the given circle, and $DEF$ the given triangle.
* So it is required to inscribe a triangle, equiangular with triangle $DEF$, in circle $ABC$.
