Dilations Assessment 2 (Common Core SRT.1)

This GeoGebra example demonstrates the dilation (scaling) transformation of a polygon about a given center, showing the original figure and its image side by side. The core mathematical concept is dilation, aligned with Common Core standard SRT.1, covering similarity, scale factor, and central projection. Construction highlights: using the Polygon command to create the original polygon poly1 with vertices A, B, C, D, then applying the Dilate command (likely centered at point E or F) to produce the image polygon poly1' and corresponding sides a', b', c', d', while retaining the original objects for comparison. This is suitable for high school geometry assessments to evaluate students' understanding of dilation properties, including identifying the scale factor and center of dilation.
