### 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!

This website has a visual dictionary of mathematical terms. Each term has visual interpretation as well as a text description.

Pull the points of a triangle to see if you made a scalene, equilateral or right triangle

Here's a set of vocabulary designed for use with Grade 3, Unit 4 of Math Expressions. The words include: parallel, perpendicular, line of symmetry, congruent, diagonal, right angle, right triangle, vertex, angle obtuse angle, acute angle, straight angle, acute triangle, obtuse triangle, ray, scalene triangle, isosceles triangle, equilateral triangle, polygon, and degree.

What is a scalene triangle?

Use this tool to move the corners to make different triangles! the angles are at the bottom left corner. Use these as a guideline to make a: equilateral triangle, obtuse triangle, acute triangle, isosceles triangle and scalene triangle. Screenshot them and make a poster to print out and show the class :) (you can use the "definition of a triangle" website to help)

This simple math quiz is suitable for grades 4 & 5 or any pre-geometry students. Students will read a geometry term and match it to its correct definition.Terms included in this quiz:* congruent* right angle* obtuse angle* acute angle* equilateral triangle* scalene triangle* isosceles triangle

### Triangles

This editable power point will help your students identify and visualize a variety of triangles. Included are definitions and examples of right triangles, acute triangles, obtuse triangles, equilateral triangles, isosceles triangles and scalene triangles with animation.

### Triangles Geometry Color Classification Worksheets

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.

Scalene, isosceles, equilateral, acute, right, obtuse. All are types of triangles but what makes them special depends on the method of categorization. Watch ...
