Valleyjournal Students write love notes to geometry Valleyjournal My conjectures are true. All I want is you. Girl, you are a right triangle. One right angle for me. You have turned a scalene triangle in an isosceles.
Proof Patterns of Congruent Triangle Proofs. The first year I taught, I noticed that students struggled with proofs. My third year, I decided to focus on building a pattern/strategy for proving congruent triangles.
