I need a non-equilateral triangle ABC and an equilateral triangle DEF to be overlapping ABC (with all 6 lines showing). Lines AD, BE, and CF need to be perpendicular bisectors (cut in the middle) of the sides of the triangle DEF. Would really appreciate any help with this thank you!

The fact that A, B, and C should lie on the bisectors makes their location unique up to a real parameter for each of them, for which I chose 1.2, 1.4 and 1.6, respectively.

documentclass[tikz,border=3mm]{standalone}

begin{document}

begin{tikzpicture}[declare function={a=2;}]

 draw (-30:a) coordinate[label=-30:$D$] (D) --

  (90:a) coordinate[label=90:$E$] (E) --

  (210:a) coordinate[label=210:$F$] (F) -- cycle;

 draw (-30-60:1.4*a) coordinate[label=-30-60:$B$] (B) --

  (90-60:1.6*a) coordinate[label=90-60:$C$] (C) --

  (210-60:1.2*a) coordinate[label=210-60:$A$] (A) -- cycle;
