In triangle FGH and triangle KLM, the measures of angles G and L are each

6 0^{\circ}

. The lengths of

\overline{G H}

and

\overline{L M}

are each 34 centimeters, and

\frac{G H}{GF} = \frac{L M}{L K}

Which additional piece of information would be necessary to prove that triangle FGH is congruent to triangle KLM?

The lengths of

\overline{F G}

and

\overline{K M}

are each 17 centimeters.

The measures of angles H and M are each

3 0^{\circ}

The measures of angles F and K are each

9 0^{\circ}

No additional information is necessary.
