Step-by-step explanation:
*To show the method of finding length of one median,taking one example.
Let
Given:Find the length of the median AP of ∆ABC whose vertices are A(–1, 1), B(5, –3) and C(3, 5).
To find:
Length of median AP.
Solution:
Draw the triangle roughly,as shown in attachment.
Since P is midpoint of BC.
Find the co-ordinate of P:
Thus,
B(5,-3)=> Let (x1,y1)
C(3,5)=>Let (x2,y2)
Co-ordinate of P
Thus,
P(4,1)
Length of Median AP:
A(-1,1) and P(4,1)
Thus,
Length of Median AP is 5 units.
