Big Ideas: The number of triangles that can be created from a condition depends on the measurements given. Estimation skills can be used to determine both the number of triangles and the types of triangles that can be created. Students have focused on triangle constructions and have categorized triangle conditions. Using this knowledge, students make estimations about the triangles they could create. Students will have to predict the number of triangles that can be created and what type of triangles will be formed. Students will have to draw on their knowledge of angles and sides relationships to make their predictions. Vocabulary: Triangle Inequality Theorem, acute, obtuse, right, scalene, isosceles, and equilateral triangle Special Materials: Rulers and protractors
