Question:
There are no data other than the data in the image
My Approach:
After a lot of time, I was only able to find two isosceles triangles as in the picture.
Thank you for attending to my question!

Only one hint, rest is straight-forward.
Apply Menelaus's theorem in triangles $ACB,$ $ADB,$ $ACD$ with respect to the traversal $FEH$. This leads you to the fact that $\triangle GDE$ is isosceles.
