For any triangle $A$ (black below), form an enclosing triangle $B$ with sides perpendicular to $A$'s angle bisectors (red). Does this triangle $B$ (blue) have a name?
A nod to vonbrand's question: This came up in exploring geodesics on a tetrahedron. It would take me far afield to explain more fully.

We could possibly call it the Anticevian triangle with respect to the incenter,
Edit: Using the above and google it seems it is called the Excentral triangle.
