Protractor compass full#
There are also 360-degree protractors that form a full circle and military protractors used for determining likely enemy positions on maps.įor serious mathematicians, there are sets that include protractors and compasses, along with other tools. In a classroom environment, a semicircular protractor is most common, featuring two types of scales, each displaying a scale that goes from 0 to 180 degrees in opposite directions. Complicating things is the fact that there are multiple types of protractors. Protractors are fairly simple tools, but there are still some features that are important. This will give you the leeway you need to make mistakes while you’re learning. You’ll also need an eraser since compass pencils typically don’t come with one. Pay close attention to the build of your compass and make sure you can find a writing implement that fits. Some compasses come with a pencil, but you may eventually have to replace it.
The more time you’ll spend with your compass, the more important those features will be. Having one that’s easy to adjust for different angles will also come in handy. If you have a compass that slips while you’re using it, your arcs will be wobbly. In a compass, steadiness is key to success. But if you’re committing to a multiyear education that includes engineering or architecture classes, it might be worth investing in a more durable set. If you just need these tools to get you through a semester or two of high school geometry, the plastic versions sold in these locations will likely do just fine. You can buy either of these tools at your local office supply store or even some grocery and discount department stores. The compass is used to draw circles and arcs, while the protractor helps you measure and make plane angles. Signing up for a geometry class means you’ll likely need two essential supplies: a compass and a protractor.
