Dynamic Geometry Proof Engine

The Problem We Solved

Most high school geometry teachers agree that proofs give their students the most difficulty. There just isn't enough practice available for the average student to confidently achieve mastery. Furthermore, most online resources can at best provide a multiple choice experience, which just isn't good enough.

Our Solution

We are proud to present what we believe to be the world's first online, fill-in-the-blank geometry proof engine with instant, intelligent grading and over 1000 different computer-generated proof problems.
