Given the line segment overline {PQ} with P = (12, 11) and Q = (8,5), the length of the line segment is a. What is a²?
Answers
Answer:
We know that by section formula, the co-ordinates of the points which divide internally the line segment joining the points (x
1
,y
1
) and (x
2
,y
2
) in the ratio m:n is
(x,y)=(
m+n
mx
2
+nx
1
,
m+n
my
2
+ny
1
)
If P and Q are the points trisection of A(−2,5) and B(3,1)
then mid-point of PQ coincides with mid-point of AB
So, m = 1 and n = 1
∴ Mid-point PQ
