Complete the following constructions to your drawing
Extend BH to AD @ J BG to DC @K
connect JK,JE,KF,JE, EK
There are congruencies leading to BG= HD BH= GD BHDG is a parallelogram
Also EJ =FK EF=JK EJKF is a parallelogram
The perpendicular distance from AC to EF and JK are equal
EF is parallel to AC.
Find the congruent parts
