This Instructional Activity is a part of the Lesson 8, Unit 6, Grade 7. In the Exploratory Challenge, students draw a triangle given two angle measurements and the length of a side. Then, they rearrange the measurements in as many ways as possible and determine whether the triangles they drew are all identical. The goal is to conclude the lesson with the question: Which pieces and what arrangement of those pieces guarantees that the triangles drawn are identical? This question sets the stage for the next several lessons.
