Givens and Results of a Tool

Each time you click as you use a tool, you are specifying a given object—an object that is used to determine the rest of the objects the tool produces. The objects produced by the tool (that depend on the given objects) are the results of the tool.

The Circumcircle tool has three givens—the vertices of the triangle. The three sides of the triangle and the circumcircle are the tool’s results.

You can think of the various objects and relationships that make up a tool as a family tree. In this family tree, the givens are the ultimate ancestors—objects that have children but no parents. The other objects—those that have parents—are the results of the tool.
