CK-12's Geometry module includes a wide variety of resources, including reading passages, pre- and post-read activities, assessments, videos, study aids, and Web links. Topic coverage is extremely comprehensive, including Definitions and Introductions to Proof, Pythagorean Theorem, Perimeter, Circumference, Area, and a whole host of others.

The videos make for great whole-class instructional support -- you can pause to address specific concerns or address potential problem areas in more detail.
