What is the correct designation for rotations in transformation geometry?

In transformation geometry, rotations are commonly denoted by the letter "R." This designation is widely accepted in mathematical conventions and literature to represent the transformation that involves rotating a geometric figure around a fixed point, typically at a specified angle.

The use of "R" helps to clearly communicate the type of transformation taking place, especially when distinguishing it from other transformations such as translations or dilations.

For instance, if a figure is rotated 90 degrees clockwise about a point, it might be represented mathematically as R(90°), indicating a rotation of 90 degrees. This consistent labeling aids in understanding and solving problems related to transformations in geometry, making it easier for students to grasp concepts related to motion and position changes of geometric figures.
