A) bisector of the third side
B) perpendicular to the third side
C) parallel to the third side
D) None of the above
Correct Answer: C
Solution :
Let \[\Delta ABC\]and D and E be mid-points of AB and AC respectively. |
\[AD=DB\] and \[AE=EC\] |
\[\Rightarrow \,\,\,\,\frac{AD}{DB}=1\] and \[\frac{AE}{EC}=1\] |
\[\Rightarrow \,\,\,\,\,\frac{AD}{DB}=\frac{AE}{EC}\] |
\[\Rightarrow \,\,\,\,\,DE\,\,|\,\,|\,\,BC\] |
[by the converse of basic proportionality theorem] |
