The first rule of life? Life (as well as geometry) can be difficult. But why make it more difficult than it has to be? Do you need help with geometry? Here are 11 tried-and-true tips to make your forays into the world of geometry as painless as possible.

1. Use a clear plastic protractor.

Tools are fun, and the dandy protractor is no exception. The clear plastic kind is especially handy because you can see through it. That way, you can extend your angles right through the scale of the protractor. Reading angle measures is much easier then.

2. Use a clear plastic ruler with inches and centimeters.

Just as with a clear plastic protractor, with a clear plastic ruler, you can extend your lines, which makes getting their measures easier. Using a ruler with inches and centimeters is a good idea. Go metric, baby!

You need to have a protractor for your angles and a ruler for your straight lines. You also need a compass — for those curved lines. Look for one that has a ruler right on it. That way, you don't have to use both the compass and a separate flat ruler when making a circle. Just pull the compass apart the distance you want and use the built-in ruler.

4. Get a good pencil to draw fine lines.

You need a pencil to make accurate drawings. Try to find a technical drawing pencil with a .05 mm lead. An eraser is an important commodity, also. You won't regret getting one that has a brush. Eraser residue leaves the page easier when it's brushed away.

5. Buy thyself a good scientific calculator.

Never underestimate the power of a good scientific calculator — the kind with sin, cos, and tan keys. You're going to need those keys on trig days. Square root and squared keys are useful for all that triangle stuff. And fresh batteries are a good idea on test day.

6. Write down your givens and wants.

When you're setting up to solve a problem, be it a proof or just an equation, write down everything you're given to work with even if it doesn't seem important. The smallest details can lead to the biggest revelations. After you finish with what you've been given, move on to what you want. Write that down, too.

7. Make diagrams.

A picture is worth a thousand words. Make a diagram with your awesome technical pencil. Try to draw things in proportion, keeping your spatial relationships intact. Mark off everything in the drawing that is in your given. If you have congruent lines, congruent angles, or parallel lines, mark 'em.

8. Develop a plan of attack.

You have your given. You've written down what you want. You've drawn your diagram. Now you have to develop a plan to solve the proof. A plan of attack can be everything from which auxiliary lines you need to draw to the type of reasoning you're going to use to solve the proof. A plan before you start gives you direction and saves on the number of steps you'll have to take to get from the given to the prove statements.
