- Perpendicular
About the Lesson
In this activity students use traditional pencil and paper techniques to construct the Spiral of Theodorus, after which they use the Geometry application on TI-Nspire to make the spiral dynamic. Students then explore consecutive hypotenuse, a series of surds, helping connect geometry and number.
