Solution Steps

Step 1: Determine the reason for congruent triangles

The given information provides two pairs of congruent angles (∠EGF ≅ ∠GEH and ∠FEG ≅ ∠EGH) and one pair of congruent sides (EG ≅ EG). These three pieces of information correspond to the Angle-Angle-Side (AAS) Congruence Theorem.

Step 2: State the reason for congruent triangles

The reason for ΔEFG ≅ ΔGHE is the AAS Congruence Theorem.

Step 3: Determine the reason for congruent segments

Since ΔEFG ≅ ΔGHE, their corresponding parts are congruent. Therefore, EF ≅ GH because Corresponding Parts of Congruent Triangles are Congruent (CPCTC).

Final Answer:

The missing reasons are:

  1. AAS Congruence Theorem
  2. CPCTC
