Answer:
D.
Step-by-step explanation:
In triangle EAK, A is the right angle.
In triangle AGK, G is the right angle.
In triangle EGA, G is the right angle.
That means we know that those letters have to be in the same position in the names of the three triangle.
The triangles are being written in the order: EAK, AGK, EGA
_A_ ~ _G_ ~ _G_
Angle E of triangle EAK corresponds to angle E of triangle EGA.
EA_ ~ _G_ ~ EG_
Angle K of triangle EAK corresponds to angle K of triangle AGK.
EAK ~ _GK ~ EG_
There is only one vertex missing in the last two triangles, so they must be A and A.
EAK ~ AGK ~ EGA
