Are you looking for a fun way to teach your students about the Triangle Inequality Theorem and the Converse of Pythagorean Theorem? Look no further! Download this two-sided worksheet that challenges students to determine how large or small a side of a triangle can be and still make a triangle. With answer key included, grading has never been easier. This worksheet is perfect for middle school math students and will help them develop their critical thinking and problem-solving skills.
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.
