Answer 1

From the question given, the reasons for the prove of the following statements are correct so far.

For the last part

`\Delta GJK\cong\Delta IHK`

The reason is Side-side-side theorem.

This theorem states that all three sides of a triangle are congruent (identical) to the corresponding sides of another triangle, then the triangles themselves are also congruent.

Hence the answer is Side-side-side theorem.
