Inequalities in Triangles Math - Geometry Grades 9-12 []

In my classroom, I would be able to use this lesson plan in order to help students create models of triangles and non-triangles. The students will use pasta to investigate the relationship between the longest side of the triangle and the sum of the other two sides. My students always have a hard time remembering how to tell if the sides form a triangle or not. I am hoping if they get to test out the relationship hands on, they will better remember how to tell if the sides form a triangle. In addition, students will measure the sides and angles of a scalene triangle and investigate the relationship between the location of the largest angle and largest side in a triangle.
