This card sort activity is the perfect way for High School geometry students to review the triangle inequality theorem and the Pythagorean theorem.  This card sort activity requires students to use the Triangle Inequality Theorem, Converse of the Pythagorean Theorem, and Pythagorean Inequality Theorems to classify triangles as Acute, Obtuse, Right, or Not a Triangle when given 3 side lengths. This high school geometry activity is so much more fun than a regular free geometry worksheet.

Triangle Inequality Theorem--A foldable and journaling for students to explain when side lengths make a triangle.

Students use the Triangle Inequality Theorem which states that the sum of any two sides of a triangle must be greater than the third to find a path through the maze. Students can also challenge one another by creating their own maze and key. Also see http://systry.com/triangle-musings/
