Reflection in x-axis, y-axis, y=x: Observe Coordinates

This example demonstrates the reflection of points across the x-axis, y-axis, and y=x axis, involving key mathematical concepts such as reflection transformations and coordinate geometry. Using GeoGebra commands like Polygon and objects A, B, C, D, one can observe the changes in coordinates before and after the reflection. Suitable for middle school and above students or teachers to understand the properties and applications of reflection transformations.
