Abstract
The ability to display an accurate image is commonly assumed to be a benefit of dynamic geometry software—it seems reasonable to conclude that the task of noticing and interpreting relationships between objects is easier if figures are drawn to scale. However, results of a study involving preconstructed, webbased, dynamic, geometry sketches in activities at the secondary school level revealed that many students either do not realize or ignore the fact that the onscreen image is accurate, and that others, who recognize and might want to use visual evidence, lack the tools to do so.
