Question

j is the midpoint of \\(\overline{fh}\\) and \\(\overline{gi}\\). complete the proof that \\(\triangle ghj \cong \triangle ifj\\).\
\

statementreason\
1j is the midpoint of \\(\overline{fh}\\)given\
2j is the midpoint of \\(\overline{gi}\\)given\
3\\(\overline{fi} \cong \overline{gh}\\)given\
4\\(\overline{fj} \cong \overline{hj}\\)definition of midpoint\
5\\(\overline{gj} \cong \overline{ij}\\)definition of midpoint\
6\\(\triangle ghj \cong \triangle ifj\\)dropdown with options: aas, asa, cpctc, definition of congruence, sas, sss

Explanation:

Step1: Identify congruent sides

We have:

  1. $\overline{GH} \cong \overline{FI}$ (Given)
  2. $\overline{FJ} \cong \overline{HJ}$ (Midpoint definition)
  3. $\overline{GJ} \cong \overline{IJ}$ (Midpoint definition)

Step2: Match congruence criterion

All three pairs of corresponding sides of $\Delta GHJ$ and $\Delta IFJ$ are congruent, which fits the Side-Side-Side (SSS) triangle congruence postulate.

Answer:

SSS
