Example code

~triangle A B C
D ;= foot A B C
E := midpoint A--B
F' N = (rotate -30 E)(extension A (foot A B C) C E)

circumcircle A B C / 0.2 lightgray /
A--B--C--cycle
A--D
B--F' / dashed blue

Generated code:

pair A = dir(110);
pair B = dir(210);
pair C = dir(330);
pair D = foot(A, B, C);
pair E = midpoint(A--B);
pair F_prime = rotate(-30, E)*extension(A, foot(A, B, C), C, E);

filldraw(circumcircle(A, B, C), opacity(0.2)+lightgray, defaultpen);
draw(A--B--C--cycle);
draw(A--D);
draw(B--F_prime, dashed+blue);

dot("$A$", A, dir(A));
dot("$B$", B, dir(B));
dot("$C$", C, dir(C));
label("$D$", D, dir(D));
dot("$F'$", F_prime, plain.N);

Which makes the diagram:
