This Instructional Activity is a part of the Lesson 14, Unit 6, Grade 7. Students use information, such as vertical angles and common sides in the structure of triangle diagrams, to establish whether conditions that determine a unique triangle exist. Students use conditions that determine a unique triangle to determine when two triangles are identical. Students construct viable arguments to explain why the given information can or cannot give a triangle correspondence between identical triangles.
