Change up your Classifying Triangles lesson & get hands on with this interactive card sort! Geometry & Middle School students will love this activity to get more practice with Triangle Classifications. Digital & PDF Printable versions are included in this distance learning ready sorting activity will strengthen students’ skill in sorting triangles into the following types of triangles categories: Equilateral, Isosceles, Scalene, Equiangular, Right, Acute, and Obtuse. Students will cut out the 18 included triangles and use the given information on each triangle to sort it into the correct spot on the chart. Distance learning? No problem! This activity now includes a Google Slides digital option!

The QR Codes next to the different types of triangles give the definitions of each type of triangle. The fact that the angles in a triangle add up to 180° (Triangle Sum Theorem) is required for some of the triangles. If doing this with younger students I recommend you quickly introduce that concept and find the missing angles in the triangles before letting the students complete the activity. There are 5 “Not Possible” cards that students will put in 5 of the squares on the chart. When classifying triangles students are expected to classify triangles into the most specific category. Thus, “Isosceles & Equiangular” is marked as Not Possible because any isosceles triangle that is equiangular is also equilateral so the most specific category would be “Equilateral & Equiangular”. The letters inside each triangle make for easy teacher checking by just checking the letter.
