## Reflection: Student Led Inquiry Types of Triangles - Section 1: Student Exploration Part 1

I act on every opportunity I get to support student-led inquiry. Here, Exploring Right Angles A.mov, two girls are developing a definition for right angles. I then ask: Can a triangle have two right angles?

To provide them with a hands-on learning opportunity for them to explore this further, I grabbed geoboard and rubber bands! The students eventually arrived at the conclusion that triangles can only have one right angle: Exploring Right Angles B.mov.
