Simple Constructions

Jump to: navigation, search

Here are some constructions of simple geometric objects. Each dynamic worksheet has the construction presented as a sequence of steps as well as illustrated with a dynamic step-by-step construction. On each page is a blank drawing pad with a limited toolbar (customized for the particular construction) for the students to try the construction out on their own.
