A rotation of a planar figure is a transformation that preserves area and angles, but not orientation. The resulting figure is congruent to the first.
Suppose we wish to rotate triangle clockwise around a point , also known as the center of rotation.
We would first draw segment . Then, we would draw a new segment, such that the angle formed is , and . Do this for points and , to get the new triangle
