Question

do any one know how to find mid points

Answer 1

As in the midpoint of a line between two points, or something else?

Answer 2

The co-ordinates of midpoint(x,y) on the line segment with end-points (x1,y1) and (x2,y2) is just the average of co-ordinates, given by :
\(\large x=\frac{x_1+x_2}{2}\)
\(\large y=\frac{y_1+y_2}{2}\)
now,just put the values and find the co-ordinates of midpoint (x,y).
