# Scalene Triangle Definition

These two geometry worksheets help students classify triangles two different ways. This 3 lesson bundle includes the following activities: • Length of Sides - equilateral triangles, right triangles, and scalene triangles • Types of Angles - acute triangles, right triangles, and obtuse triangles. A definition of each type of triangle is listed at the top of each worksheet. Students color each triangle following the directions at the top of the pages.

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!
