In collections Dilation Introduction
This example demonstrates how students explore the effects of the center of dilation and the scale factor on a figure. Students can observe what happens to a triangle when it undergoes a dilation. Key math concepts include dilation, scale factor, and center of transformation. Construction highlights the use of GeoGebra commands like Segment, Dilate, and Line, along with objects such as points and figures. Suitable for middle school and above students learning geometric transformations.
