Answer 2

Answer:

A median of a triangle is a line segment that joins the

vertex of a triangle to the midpoint of the opposite side.

Mid point of two points (x

1

,y

1

) and (x

2

,y

2

) is calculated by the formula (

x

1

+x

2

,

2

y

1

+y

2

)

Since AD is the median, this means, D is the mid point of BC.

Using this formula, mid point of BC =(

Distance between two points (x

,y

) and (x

,y

2

) can be calculated using the formula

(x
