Given: ≅ and ≅
Prove: ≅
According to the given information, ( ) is congruent to ( ) and ( ) . ∠ ( ) should be congruent to ∠ ( ) by Vertical Angles Theorem. Since ( ) is congruent to ( ), ∠ ( ) is congruent to ∠ ( ), and is congruent to , △GHF is congruent to △JHI by ( )
. Then, one can assume that is congruent to by ( )
"( )" means fill in the blank
