now what

Which congruence test can be used to prove that triangle GHI =~ triangle LKJ?

ok                            __      __
angle G =~ angle L    GJ =~ LJ
                                __      __
angle H =~ angle K    HJ =~ KH
                                      __       __
angle GHJ =~ angle LKJ    HG =~ LK

Re: now what

The congruency test is ASA (Angle, Side, Angle)

GJH ~ LJK [horizontally opposite angles
HJ ~ JK  [given
GHJ ~ LKJ [given

So you say,
GJHb2dea18d635a215a1f91b672d7c2fbdc.pngLJK by ASA.

take away the brackets in the picture
