In this activity, students will use their Nspire handhelds to discover the different points of concurrencies in triangles. The students will take advantage of the dynamic capabilities to discover the circumcenter, incenter, and centroid of triangles.
Before the Activity
This activity is designed for use in a Geometry classroom. Prior to beginning this activity, students should have prior knowledge of perpendicular bisectors, angle bisectors, medians, vertices of triangles, and the different types of triangles.
During the Activity
This activity is intended to be a teacher-led activity in which students will make their own discoveries pertaining to the points of concurrency of triangles. Students should be encouraged to make predictions of how the points of concurrency will behave if the vertices of the triangle are translated.
