Students will explore the triangle inequality theorem by trying to create their own triangles with various side lengths. Students will cut out strips of paper to represent the side lengths of the triangles, then will put a given three together to test and see if a triangle can be formed. Students will test a total of 20 sets of three, and will discover that if the shorter two sides have a sum greater than the longest side, they can make a triangle. Students will then apply this rule to application questions. By the end of this lesson, students will have a deep understanding of the triangle inequality theorem.
