Line joining vertex to mid point of opposite side of a triangle is median of a triangle.
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
For an obtuse angled triangle ∆ABC
For obtuse angled triangle ∆ABC
For right angled triangle ∆ABC
