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.

Angles of Triangles Cut, Paste, Solve, Match Puzzle ActivityIn this activity, students cut out 36 puzzle pieces that represent the different types of angle relationships that can be be created by the angles inside and outside of triangles (angle sum theorem, exterior angle theorem, vertical angles, the Isosceles Triangle Theorem).Each puzzle includes:** A diagram** The value of x** The value of a requested angleStudents need to match the pieces together and use the given information to solve…

Right Triangle - Angles of Elevation & Depression Interactive Notebook PagesIn this fantastic set of Interactive Notebook Pages you will find two separate pages - one on angles of elevation and one on angles of depression. I have created them in two versions - one with each type double printed so you can give do the topics separately and one with both topics on the same page.

Do your students have trouble knowing which leg is the opposite leg or which one is the adjacent leg with respect to an angle in a right triangle? One of the first lessons when learning trig ratios is to find these sides. This game was created to help students get practice finding those sides in a fun way.
