Conjecture and Proof in Geometry.pdf (145.6 kB)

---

Many geometry texts focus on proving triangles congruent under a variety of conditions. In this presentation, we start from a property common to all quadrilaterals and prove that it is a common property. Then we extend our thinking to a set of conjectures that students can come up and then actually prove by themselves.
