Given: verify section formula by graphical method
To Find : verify
Solution:
Coordinates of points A are ( 1 , 1)
Coordinates of points B are ( 6, 6)
Point C Divided AB into 2 :3 ratio
Coordinates of point C from Graph paper are ( 3 , 3)
Coordinates of point C using section formula ( 3 , 3)
using Section formula
(2 * 6 + 3 * 1)/(2 + 3) , (2 * 6 + 3 * 1)/(2 + 3)
= (12 + 3)/5 , ( 12 + 3)/5
= 15/5 , 15/5
= 3 , 3
Coordinates of point C from Graph paper and using section formula are Same ( 3 , 3)
