Line joining vertex to mid point of opposite side of a triangle is median of a triangle.

 

For ∆ABC

Here, AD is the median of triangle ∆ABC

& D is mid-point of BC.

 i.e. BD = CD

 

Similarly, we can draw median from point B

Here, BE is the median of ∆ABC

& E is the mid point of AC

i.e. AE = EC.

 

And, we can draw median from point C

Here, CF is the median of ∆ABC

& F is the mid point of AB.

i.e. AF = FB.

 

So, our median can be
