Rotation

Explain in Detail :Rotation Matrix

A rotation matrix is a mathematical object that describes a rotation of a coordinate system around a point in space. It is a 3×3 matrix that has the following form:

[math]\begin{bmatrix}1&0&0\\0&1&0\\0&0&1\end{bmatrix}[/math]

The rotation matrix rotates the coordinate system around the point [math] (1,0,0) [/math] by the angle [math] \theta [/math].

Rotational Symmetry

A shape has rotational symmetry if it can be rotated around a point and look the same.
