Secrets in the Triangle

Published on 10/27/2008

Activity Overview

Students will use the geometry screens of the TI-Nspire™ to find points of concurrency by constructing the altitudes, perpendicular bisectors, and medians in triangles. The Euler Line will be found and extensions given.

Before the Activity

Students should know definitions of altitude and medians of a triangle, also perpendicular bisectors and angle bisectors in triangles.
