This week we have been learning about rotations.Rotation in mathematics is a concept originating in geometry. For example, the motion of a rigid body around a fixed point. A clockwise rotation is a negative so a counterclockwise turn has a positive. For example, A(0,1) B(4,1) C(2,5) then you change the positive points unto negative points A(0,-1) B(-4,-1) C(-2,-5).
