Drag Test

When you construct a shape in GeoGebra, if you have constructed it correctly, it should always remain that shape, regardless of how you drag the vertices. This is what it means to "Pass the Drag Test."

You can click on the RESET ICON in the upper right hand corner of each sketch to reset the sketch.

In the sketch below are four squares. Which squares pass the DRAG TEST?
