Chord Exploration

In this exploration, you will discover mathematical relationships involved with chords and secant segments, and tangents in circles. The first phase has the exploration set up for you. The rest of it you will need to create on your own.
Using this application, deduce a relationship between the segments created when two chords intersect inside the same circle. After you've discovered a consistent relationship, write down what you think the theorem statement should be to describe the phenomenon.
