#GEOGEBRA CLASSIC VS GEOMETRY FOR FREE#
And Geogebra's ability to be downloaded for free on any computer makes it the clear choice for any educator. But there's no advantage it has over Geogebra. That said, Geometer's Sketchpad is still a great program. On the one hand, GeoGebra is an interactive geometry system (freely available from ). (I believe it translates all points A, B, C, D by the same translation as on E - probably the best choice if a move is to be made) The flexibility is "nice" to create desired images, but Geogebra's structured dependencies are an asset towards the structures of geometry. GeoGebra represents dynamic mathematical software for all levels of education that joins arithmetic, geometry, algebra and calculus. but how? Sketchpad necessarily makes an arbitrary choice to redefine objects. If Sketchpad allows E to be dragged it means AB and CD must move also. You can't drag point E because E is defined to be the intersection. I feel that Geogebra is correct in not allowing you to drag (some) intersection point(s): the way objects are defined is rigorous.
Die folgende Tabelle gibt einen berblick darber, welche Funktionen in welchen Apps verfgbar sind. In Sketchpad, they point out as a feature that you can drag the intersection point of two lines, noting that Geogebra can't do this. GeoGebra Classic ie richtige App fr dich ist die, die deinen eigenen Bedrfnissen entspricht und, wenn sie in Prfungen verwendet wird, die Prfungsbestimmungen fr deine Region erfllt. And who can say that intersecting a line with a locus "belongs" to Sketchpad?Īlso, Geogebra's structures feel more logical. I don't know if anyone "stole ideas" but I do know it wouldn't matter. This is the key point: Geogebra will evolve faster. Sketchpad's publishers put out a comparison of features here: but its mainly nitpicks, or things that can be avoided, or things that have since been changed.
#GEOGEBRA CLASSIC VS GEOMETRY UPGRADE#
They can't develop as quickly, and people are reluctant to upgrade to new versions if they cost money.
I know Sketchpad was developed first (since the 90s), but because it is commercial it is inherently handicapped. When he put it out online everybody loved it and since its open source, it has been gaining developers ever since. I know that Geogebra was initially a project created by grad student Markus Hohenwarter in Salzburg, Austria around 2001-2005, and brought it to the U.S.
