In this quiz game, you test your geometry skills by solving a variety of angle questions. Each question shows you a diagram with a collection of lines and angles, and asks you to find the missing angle, labeled **x ^{o}**.

**The geometry facts you'll need to know to do well are :**

- What the angles in a triangle add up to...
- What the angles in a quadrilateral add up to...
- Facts about angles and parallel lines...
- Angles between lines at their intersection...
- The total of angles on a line...
- The total of angles around a point...

You should see the angle geometry quiz game just above this paragraph. If you can't see it, ask the person in charge of this computer to make sure "Java" is installed (you can download it from Sun Microsystems), including the correct "Java Plugin" for your browser.
