If you're frustrated with geometry, math help is on the way.

At the bottom right corner of your screen, type (or copy and paste) the question with which you need help into the dark gray chat box.

If you can wait 20 minutes or so, let me know if you'd prefer a video tutorial.

You'll soon get quick, simple steps for solving your problem. This math tutoring chat is perfect for word problems.

What if it says "Leave a message," not "Chat with us"?

If the bottom right corner of your screen says "Leave a message," that means I'm offline. Click on it and send me the text of the problem you need help with. Please mention that you're in geometry (or whatever the name of your math class is). It will ask you for your name and e-mail address. I value your privacy and will not share or sell your e-mail address.

Within 24 hours, I'll e-mail you the link to a video showing you how to solve the problem.

Is this a good resource for taking tests?

No, this website is not appropriate for tests. That would be cheating. We prepare for tests by studying and practicing. Use this website for homework, practice problems, or sample problems.

Circles and Tangent Lines

The following video solves this problem from Geometry B:

BC is tangent to Circle A at B and to Circle D at C. AB = 10, BC = 12, and DC = 5. Find AD.

In this video, we use the Pythagorean Theorem to calculate the length of the line.
