Importance Of Compass And Straightedge

Compasses and straightedges are tools used regularly in geometry. Compasses are used to draw precise circles and arcs, leading to making many geometric figures. Straightedges are used to make straight lines that are exact measurements. There is a need for students to understand and be able to construct geometric figures using a compass and straightedge. This is because students will be able to understand the steps it takes to construct geometric figures, it allows students to understand how to use other geometric tools easier, and it is likely for less mistakes.
To start, students need to understand the steps to construct geometric figures. Using computer programs to make geometric figures is just a click of few buttons, while using a compass and straightedge, students will make the measurements and construct the figures by hand. According to geometrictool.com, "You could be in a situation where your device that has the drawing program is not working. You may need to make adjustments to your figures and doing it with a compass and straightedge might be …show more content…
Computer programs are not very good because they can cost lots of money, they are hard for students to understand, and students don't memorize how to actually construct the figures on a program.
First of why computer programs are not good is that some cost way more than just using a compass and straightedge. Although there are some free geometry programs, they don't have tools in the program and it's just a gridded screen that you can draw on. That can be easily accessible on graph paper with a pencil. Plus, compasses and straightedges can both sell for under a dollar and still work to make precise measurements. Most students can’t afford high end or accurate geometry programs but they can easily get a compass and
