In this activity, students will use GeoGebra to construct using technology the circumcenter, incenter, centroid and orthocenter of triangles.
Understanding vocabulary is critical in order to fully understand triangle relationships. In this activity, students will review the vocabulary associated with triangles: circumcenter, incenter, centroid, and orthocenter.
I had my students cut out the flashcards during class. I was very surprised some students took a lot of time cutting out the cards since they cut around the boxes instead of making straight cuts.
I would suggest before students are given the scissors, to model the quickest way to cut out the cards.
In this activity, students will construct using a compass and straightedge the points of concurrency in triangles: centroid, incenter/incircle, circumcenter/circumcircle, and the orthocenter.
