Using the TI-Nspire™ CX II Graphing Calculator to Explore Unexpected Circles Associated With a Triangle

When: Tuesday, Jan. 21, 2025 | 7 p.m. Central time
Technology: TI‑Nspire™ Series
Presenters: Troy Jones, Steve Phelps

Most geometry teachers and their students are familiar with such circles as the circumcircle and incircle of a triangle.

But what about the excircles? Or the nine-point circle? Or Yff circles? Or Miquel circles?

There are these circles and so many more to explore, and we will use the TI-Nspire™ CX II graphing calculator to explore as many as we can in an hour!

Join the live webinar for the chance to win a TI graphing calculator. (Download drawing rules.)
