Question

Write down the Section Formula.​

Answer 1

Step-by-step explanation:

a point P = (x , y)P=(x,y) divides the line joining two points A = (a , b)A=(a,b) and B = (c , d)B=(c,d) in the ratio m : nm:n internally, then the coordinates of PP are given by

P~(x , y) = \left (\dfrac{c \cdot m + a \cdot n}{m + n} , \dfrac{d \cdot m + b \cdot n}{m + n} \right).

P (x,y)=(

m+n

c⋅m+a⋅n

,

m+n

d⋅m+b⋅n

).

If PP divides ABAB externally in the ration m : nm:n, then

P~(x , y) = \left(\dfrac{c \cdot m - a \cdot n}{m - n} , \dfrac{d \cdot m - b \cdot n}{m - n} \right).

P (x,y)=(

m−n

c⋅m−a⋅n

,

m−n

d⋅m−b⋅n
