A;H;D;G
Step-by-step explanation:
Altitude is a line from a vertex that intersects a side at a 90 degree angle. DE is the only altitude shown
Perpendicular bisectors divide a side into 2 congruent pieces, at a 90 degree angle. GB is the only perpendicular bisector shown.
An angle bisector is a line that divides an angle into 2 angles with the same measure. CF is the only angle bisector shown.
A median is a line that goes through a vertex and divides a side into 2 congruent lengths. AB is the only such example.
