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!

Classifying Triangles Card Sort

By the end of the activity student should be able to identify what type of triangle each triangle is based on prior knowledge.

Definitely using this as a lesson opener for special right triangles.

My Geometry students loved this proof activity!  It was the perfect geometry worksheet alternative to help my High School Math students gets some hands on Proof practice.  I loved how they had to use the different triangle concurrency theorems to prove triangles congruent.  I will definitely be doing this activity with my High School Geometry students every time I teach Geometry proofs.

Triangles are polygons with 3 sides and 3 angles which always add up to Types of triangles may be classified by their sides, by their angles or by a combination of both sides and angles.
