Question

write section formal for internal divison​

Answer 1

Answer:

Section Formulae at a Glance

Step-by-step explanation:

For Internal DivisionP={[(mx2+nx1)/(m+n)],[(my2+ny1)/(m+n)]}

For External DivisionP={[(mx2-nx1)/(m-n)],[(my2-ny1)/(m-n)]}

Midpoint FormulaP={(x1+x2)/2,(y1+y2)/2}

Answer 2

Answer:

Suppose a point divides a line segment into two parts which may be equal or not, with the help of the section formula we can find that point if coordinates of a line segment are given and we can also find the ratio in which the point divides the given line segment if coordinates of that point are given.

When a point C divides a line segment AB in the ratio m:n, then we use the section formula to find the coordinates of that point. The section formula has 2 types. These types depend on point C which can be present between the points or outside the line segment.
