Given : QS is median drawn from the vertex Q on the side PR
T is a point on SQ, such that ST =1 unit.
To Find : the coordinates of point T
Solution:
P= (3 , -1)
Q = (7 , -3)
R = (5 ,3 )
QS is median
Hence S is mid point of P & R
=> S = ( 4 , 1)
Q = (7 , -3)
QS = √(7-4)² + (-3 - 1)² = 5
QS = 5 unit
T is on QS
and ST = 1 unit
=> QT = 5 - 1 = 4 unit
=> T divides SQ in 1 : 4 Ratio
S = ( 4 , 1) , Q = (7 , -3)
=> T = ( 1*7 + 4*4)/(1 + 4) , ( 1 * - 3 + 4 * 1)/( 1 + 4)
=> T = ( 23/5 , 1/5)
coordinates of point T.
( 23/5 , 1/5) or ( 4.6 , 0.2)
