### Classifying Triangles Card Sort

My Geometry students loved this! This Classifying Triangles card sort worksheet activity was the perfect activity for my Middle School Math & High School Geometry students to practice sorting triangles by their angle and side measurements. Students had to figure out if the triangles with Equilateral, Isosceles, or Scalene. Then they had to figure out if they were Equiangular, Right, Acute, or Obtuse Triangles. I will definitely be doing this in our math interactive notebooks again!
