Observe the Effect of Scaling on an Image.
Here is a portrait of a student. In this activity, you are going to interact with the portrait to discover scaling.
To Match Scaled Copies of Polygons.
In the applet below is a set of cards that have polygons drawn on a grid.
(1.) Explain or show how you know that one polygon is a scaled copy of the other.
(2.) Is it possible to draw a polygon that is a scaled copy of both Polygon A and Polygon B? Either draw such a polygon, or explain how you know this is impossible.
