1.	A(1,2) B(-2,-5) C(2,1).find its G and length of median through A
Answer» ER: Coordinates of A≡(−1,3) Coordinates of B≡(1,−1) Coordinates of C≡(5,1) The median through the vertex C will MEET at the mid point of AB. Coordinate of mid-point on AB=( 2 (−1)+1 , 2 3+(−1) )=(0,1) Now, LENGTH of median through vertex C= Distance between (5,1) and (0,1) Therefore, Length of median = (0−5) 2 +(1−1) 2 ⇒ Length of median = (5) 2 =5 units Hence the length of median through the VERTX C is 5 units. Step-by-step explanation:

Answer» ER:

Coordinates of A≡(−1,3)

Coordinates of B≡(1,−1)

Coordinates of C≡(5,1)

The median through the vertex C will MEET at the mid point of AB.

Coordinate of mid-point on AB=(

(−1)+1

3+(−1)

)=(0,1)

Now,

LENGTH of median through vertex C= Distance between (5,1) and (0,1)

Therefore,

Length of median =

(0−5)

+(1−1)

⇒ Length of median =

(5)

=5 units

Hence the length of median through the VERTX C is 5 units.
