Unit 6, Lesson 8# Drawing Triangles

EngageNY 45 min(s)

Students draw triangles under different criteria to explore which criteria result in many, a few, or one triangle. Students should end this lesson understanding the question that drives Lessons 8-11: What conditions (i.e., how many measurements and what arrangement of measurements) are needed to produce identical triangles? Students arrive at this question after drawing several triangles based on conditions that yield many triangles, one triangle, and a handful of triangles. After each drawing, students consider whether the conditions yielded identical triangles.
