Hi,

triangle with vertices A(3,8) B(7,2) and C(0,1), find the length of the median drawn to the side BC

Midpoint of BC: Midpoint  Pt(x,y):  ( %28x%5B1%5D+%2B+x%5B2%5D%29%2F2, %28y%5B1%5D+%2B+y%5B2%5D%29%2F2++%29)

B(7,2) and 

C(0,1) Midpoint (3.5,1.5)

the length of the median:

Distance:  D = sqrt+%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29%29

(3.5,1.5)

(3,8)      D = sqrt%28%28.5%29%5E2+%2B+%28-6.5%29%5E2%29
