Geometric Transformations in the Plane: Examples

This lecture covers examples of geometric transformations in the plane, focusing on rotation and reflection. The instructor explains how to determine the analytical formulas for rotations and reflections, providing step-by-step solutions for each case. Through these examples, students learn how to identify the characteristic elements of each transformation and understand the geometric nature of the resulting figures. The lecture also delves into the concept of angle rotation and center of rotation, illustrating how these parameters affect the transformation outcomes.
