You'd have to show $\ast$ is associative, that $(0,0)$ is the identity, and that: I've also taken certain liberties writing the congruence class of an integer as that integer, to avoid a lot of extra brackets, and stuff. A reflection leaves only the axis of rotation fixed, while a reflection followed by a different reflection leaves only one point fixed-the intersection of the two axes of reflection , so it must be a rotation since only a rotation leaves a point fixed. Rotation, Reflection, and Frame Changes Orthogonal tensors in computational engineering mechanics R M Brannon Chapter 3 Orthogonal basis and coordinate transformations A rigid body is an idealized collection of points (continuous or discrete) for which the distance between any two points is xed.

In SI units, it is measured in radians per second. I'll call $r$ a "click". So we know that consumed. Rotation: Any 2D rotation transformation is uniquely defined by specifying a centre of rotation and amount of angular rotation, but these two parameters don't uniquely define a rotation in 3D space because an object can rotate along different circular paths centring a given rotation centre and thus forming different planes of rotation. Any translation can be replaced by two rotations. Use pie = 3.14 and round to the nearest hundredth. Order matters. You are being asked to find two reflections $T$ and $S$ about the origin such that their composition is equal to $R_\theta$; that is, $T\circ S=R_\theta$.
