Defining a Rotation

This example demonstrates how to define a rotation transformation using GeoGebra, rotating a polygon around a specified point by a certain angle. Core mathematical concepts include rotation transformation, geometric construction, and coordinate geometry. Key construction elements involve commands like Polygon, points A, B, C, D, angles q1, q2, and parameters a, b, c, d, transformed points A', B', C', D'. Suitable for high school geometry teaching to help students understand the principles and methods of rotation transformation.
