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

AI Thread Summary
To determine the new coordinates of a polygon, specifically a triangle, when inclined at a certain angle, a clear problem statement is essential. The original coordinate system must be defined, as the inclination may alter the meaning of the x and y coordinates. The discussion suggests using the triangle law of sines to calculate the new point. Without a precise understanding of the inclination and coordinate directions, the problem remains ambiguous. Clarity in these aspects is crucial for accurate calculations.

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.
 
Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
