I am using the (=) sign to represent congruent.
statement:..................................Reason
ABD (=) EFH.............................. Given
CBD + ABD =90............................ Given
GFH + EFH =90............................ Given
GFH + ABD =90....................... substitute ABD for EFH since ABD (=) EGH
GFH + ABD = CBD + ABD............... since both are equal to 90 they are also
...................................... equal to each other.
GFH = CBD............................. subtracting out equal angles
GFH (=) CBD........................... conclusion
