**Rotation**and translation are affine transformations. So if you have a set of points... will be the same as the corresponding two points in Y. So, in summary, rotations and translations are affine transformations and therefore: 1) Angles are...2 Answers · Science & Mathematics · 14/12/2008

**Rotation**by half the angle. If R(theta/2) is the**rotation**matrix for angle theta/2, R(theta/2)*R(theta/2) is two rotations by theta/2, equivalent to a single**rotation**by theta which is R(theta).. .2 Answers · Science & Mathematics · 01/03/2013

**Rotation**by counterclockwise is the same thing as pretending the positive y-axis... you see how that gets you the result? If not, try to prove that**rotation**is a linear transformation (there is a nice way to do this geometrically) and...2 Answers · Science & Mathematics · 21/04/2009
