Once you have graphed the circle, you can find its area by tapping on the angle icon at the top of the page, selecting area, and then tapping on the perimeter of the circle. All you have to do is tap on the circle icon at the top of the screen, choose either of the first two options, and draw your circle where desired. However, what I find most interesting about the graphing capabilities of GeoGebra is you can easily graph a circle, see its equation, and find its area. You can graph various functions, find points of intersection, and observe how a function changes using sliders. The graphing capabilities are similar to those of Desmos. However, I highly encourage you to explore the other options available to fully understand what GeoGebra has to offer. On the table of contents bracketed above, it lists graphing, Geometry, 3D graphics, CAS (Computer Algebra System), spreadsheet, probability, and exam mode.Įven though I cannot begin to cover everything that GeoGebra offers, I will give you what they call a “Crash Course” on the graphing and geometry capabilities. When opening the classic version of GeoGebra, this is what the home screen looks like: The app is more condensed, so it is just the classic version of GeoGebra. The GeoGebra website offers the classic version of GeoGebra along with classroom resources with over 1 million free activities, simulations, exercises, lessons, and games for math & science.
