find the points of trisection of the line segment joining 12,0 and -6,5
Answers
Answer:
I now the answer my friend
Given : line segment joining the (12,0) and (-6,5).
To Find : coordinate of the points of trisection
Solution:
Let say
P = ( 12 , 0)
Q = (-6 , 5)
Points A & B Trisect PQ
such that PQ
A divided in 1 : 2 Ratio & B divides in 2 : 1
P = ( 12 , 0) Q = (-6 , 5)
A divided in 1 : 2
A = ( 1 * (-6) + 2 * 12)/(1 + 2) , ( 1 * 5 + 2 *0)/(1 + 2)
A = ( -6 + 24)/3 , ( 5+0) / 3
A = 18/3 , 5/3
A = 6 , 5/3
P = ( 12 , 0) Q = (-6 , 5)
B divided in 2 : 1
B = ( 2* (-6) + 1 * 12)/(1 + 2) , ( 2 * 5 +1 *0)/(1 + 2)
B = ( -12 + 12)/3 , ( 10+0) / 3
B = 0/3 , 10/3
B = 0 ,10/3
P = ( 12 , 0) A = (6 , 5/3) , B = (3 , 10/3) , Q = (-6 , 5)
(6 , 5/3) and (3 , 10/3) trisect line segment joining the (12,0) and (-6,5).
