How to rotate a triangle 90 degrees
Web90 Degree Rotations. Conic Sections: Parabola and Focus. exampleWebGiven any point p = [ x y] and a center of rotation c = [ a b] we can construct the vector d → = p − c which is the vector that goes from p to c. Then we can create a rotation matrix T = [ cos θ − sin θ sin θ cos θ] where θ is the counter-clockwise rotation angle. Then the rotated point p ′ is given by. p ′ = T d → + c.
