#6.4 The Triangle Midsegment Theorem

How can you show that the midsegment $\overline{ED}$  is parallel to  $\overline{BC}$  ?

• Find and compare the lengths of  $\overline{ED}$  and  $\overline{BC}$  

• Find and compare the slopes of  $\overline{ED}$  and  $\overline{BC}$  

• Find and compare the midpoints of  $\overline{ED}$  and  $\overline{BC}$  

• You cannot show that the midsegment $\overline{ED}$  is parallel to  $\overline{BC}$
