How to get the new Coordinate of an Polygon at angle X

  1. Mar 7, 2012 #1
    Let say I have a triangle(polygon). I know all the co-ordinates of all points(x1,x2,x3,y1,y2,y3). Let say the polygon is inclined(at x3,y3) and it's angle is 30 degree. How to get the point x4, y4?

    You have not given a clear problem statement at all. To start, you have not really stated what the coordinate directions x and y are. Then you speak of the polygon being inclined; do you mean that it is tipped out of its original plane? If so, it would seem that the implied original x and y coordinates no longer have any meaning at all.

    I suggest you try all over again, being sure that we can tell what you intend to say.
