Can someone me out with this question

Make sure to notice where the triangle is said to be congruent.

(triangle) GHI is congruent to (triangle) LMN

<G= <L, <H= <M, <I= <N

GH= LM, HI= MN, GI= LN.

"C" is correct.

"D" is correct.

"E" is correct. 

I hope this helps!

angle L = angle G
angle M = angle H
IH = NM

Explanation:
In writing congruent triangles, the order of writing the letters is very important. This is because each side/angle in the first triangle will be congruent to its corresponding side/angle in the second triangle.
Now, we are given that:
ΔGHI ≡ ΔLMN
This means that:
For angles:
angle G = angle L
angle H = angle M
angle I = angle N
For sides:
GH =LM
HI = MN
GI = LN
