I have the {x',y'} coordinates values and I'm trying to rotate this blue coordinate system to get {x'',y''}.
The coordinates of P2 point in {x2',y2'} are {200,200} and I know that the final coordinates in {x2'',y2''} are {282.84,0}.
I have calculated the slope of the p1-p2 line in order to get {x2'',y2''} but I don't know how to get {282.84,0}
Description of the problem mentioned aboved
So, how could I get the {x'',y''} of the points P2,P3,P4 in the image?
