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
