Which explains whether Triangle FGH is congruent to Triangle FJH?

Answer:
The correct answer is third option
They are not congruent, because only one pair of corresponding sides is congruent.
Step-by-step explanation:
From the figure we can see that, two isosceles triangles.
ΔFGH and ΔFJH
We get FG = GH and FJ = HJ
And side FH is common for both the triangles.
We can not say these two triangles are congruent.
