Explanation:
1. Yes, there is enough information.
The three sides of one triangle are shown to be congruent to the three sides of the other triangle, so by SSS the triangles are congruent.
2.
AB = GF = 5
AC = HF = 3
BC = GH = √[(-7 + 4)² + (0 - 5)²] = √34
All sides of triangle ABC are congruent tot eh corresponding sides of triangle FGH, so by SSS the triangles are congruent.
