hi, im using excel to calculate if a plane is within limits (cog) and im nearly finished. Im trying to set a warning for when it goes outside limits, represented on a graph, i need a formula to find if a point is within a givin area, i have the points of the area say, A,B,C,D it is not a perfect square or a rectangle. so if anyone can help i would greatly appreciate it.
its not a triangle it has 6 points, i know the co-ordinates of each, and have 5 points that make up a line that are to be plotted, for each of those plotted points i need a formula to find if those points are in the area of the 6-pointed shape, i have co-ordinates of all points mentioned.
Hexagon - Wikipedia, the free encyclopedia
But not always a hexagon; like, if 3 points are collinear, you end up with a pentagon;
but I guess that's beside the point...
All to say that I don't know! I'll guarantee it won't be something simple
On the positive side, there are geometrical whizzes here: perhaps they'll step in
and save the day
