After experiencing three geometry technologies: Desmos, Geogebra, and Geometry Sketchpad, I can confidently say that all three were very much new to me. Nevertheless, they were relatively among the three, I would choose Geometry Sketchpad to be the hardest one.
You may ask why Geometry Sketchpad? While it is true that Geogebra was a bit hectic to navigate around, but GSP was a true chaotic nightmare at a first glance. First of all, since the developers quit updating the software (and sarcastically speaking, no wonder why), the program looks very outdated overall–to the point it seems that GSP would look its best with a Window XP.
In addition to GSP, on a first glance, all the menues and tabs are overwhelmingly copious. It almost feels like showing up early to a blind date, and the place is packed with single men, so you end up with someone whose name you think is John–along with a dirty martini in your right hand.
The hectic-ness of GSP also applies to Geometry. Thus, Desmos wins my preference for geometry applications.
Nevertheless, these softwares helped me review some of deep geometry concepts all the way back from freshmen year of high school, which I did not learn anything “new” in mathematical sense–just technology. Along with that, I personally would love to teach high school geometry. Not only would it be nostalgic, but I will have the convenience of having the students explore the concepts through these softwares, instead of me having to explain everything in details. Also, the technologies are an excellent ways to provide visualization of not only shapes, but also angles and lengths, which would save everyone from having to measure everything by hand.
Overall, I have developed a love-hate relationship with these softwares, but nevertheless, I cannot deny that they are undoubtedly helpful.
