Things to Know Buying Geometry Compass
1. Who Needs It
It’s important to clarify who will use the compass. If kids, then it’s not required to buy the high-end model. Also, it should come with a great set of rulers and other needed tools. Even, the case can be a saver to keep all stuff in one place.
However, if the users are high school students or college, then you may need to stay away from the cheap plastic compass that will commonly fail soon. In the same way, a woodworker also needs the same quality products.
2. The Locker / Fastener
You know that it’s easy for the compass to slide out and change the diameter that we have set up. It can change the whole size of the circle. This is the benefit of the fastener. It locks both the legs of the compass and makes them stay spaced as adjusted before.
The marker has to be changeable. If you are going to use a pencil or pen as the marker, you are allowed to do it easily. If your compass marker is not changeable, then you must carry more than one type of compass.
4. Supports Long Diameter
Sometimes, we are going to draw a big circle. A big circle means wide diameter. The circle with wide diameter can only be drawn by a long leg compass. Unfortunately, the leg length is limited. Here some brands come with an extender along with their products.
This extender will add up the capability of the compass to draw a circle with wide diameter. In addition, you just need to install it on one of the legs. If you are finished with your work, you can save it again without being too big or long in the compass case.
How to Use A Compass for Geometry?
Using a compass is very easy. Firstly, extend the legs to a given length. Use the ruler to measure the length of its extension. To get an accurate span, use the wheel center. It’s a useful feature to make a small adjustment. Then, put the needle at the point you want, and put the second leg where the lead or pencil sticking into another point. Then turn around the leg where the lead or pencil sticks in. Turn until the lead or pencil draws the line and the line continues to connect. It becomes a circle now.

You need to remember that there are two common types of compass for geometry: graphic compass and study compass. The study compass is the compass that you can change the marker whether it’s a pencil, mechanical pencil, colored pencil, and even a pen. While the graphic compass is that is using leads. Just to make some settings before using a compass whether you are more preferable to use the study or graphic.
