[DotNetDevelopment] C# Geometry / Trigonometry Question

[Michael]

How do I get the coordinates for inflating points of a polygon away
from a center point?

based on the  PointX PointY and CentroidPointX CentroidPointY  what is
the formula to get the new points?

Inflate by 1

PointX = -20
PointY = -37

CentroidPointX = -2;
CentroidPointY = 3;


What is?

InflatedPointX
InflatedPointY

I am not sure if I am on the right track here.

private static Point Inflate(Point centroidLocation, Point
pointLocation, Double change)
        {
            Point rPoint = new Point(centroidLocation.X,
pointLocation.Y);
            Double slope = GetSlope(centroidLocation, pointLocation);
            Double hypotenuse = GetHypotenuse(rPoint.X -
pointLocation.X, centroidLocation.Y - rPoint.Y) + change;
         ??????????????????????????
            return......
        }
