Three quadrilaterals exist such that GHJK ≅ ASDF and GHJK ≅ VBNM.If MV measures 3 cm, which other segment must measure 3 cm?

In the congruence GHJK ≅ VBNM, the matching vertices are G↔V, H↔B, J↔N, and K↔M. So segment MV corresponds to segment GK, which also measures 3 cm. In GHJK ≅ ASDF, segment GK corresponds to AF, so AF measures 3 cm.
