Study Buddies: Classifying Triangles

What can symmetry tell us about triangles? After looking at four examples, learners will come to realize that lines of symmetry are different for equilateral, isosceles, and scalene triangles. Use this guided practice activity as an...

For this classifying triangles worksheet, learners solve four multiple choice problems where they classify triangles as scalene, right, isosceles, and equilateral.

Here is a classifying triangles practice activity in which learners sharpen their problem solving skills as they solve six story problems.

Learners examine a figure made up of different types of triangles and then determine whether each triangle is right, acute, or obtuse. Next, they color each type of triangle a different color. Finally, pupils answer three fill in the...

Learners study acute triangles. They measure angles using a protractor, then classify the triangles as either right, obtuse, or acute. Everyone creates a design for a Navajo rug using only acute triangles.

Learners study the triangle. They read and discuss the book, The Greedy Triangle and create a circle map about polygons. They use Microsoft Word to complete a Polygon Chart and complete a Jeopardy game on the Internet. They complete a...

How would you classify this triangle? Learners examine nine triangles to determine if they are isosceles, scalene, or equilateral. They also indicate whether the angles are right, obtuse, or acute. Each shape is pictured and has side...

Even though there is a wide variety of different triangles in the world, knowing a single equation allows us to find the area of each and every one of them. Follow along with this step-by-step presentation as Zoe clearly models how to...

Jam on with this multi-faceted activity teaching triangle classification. Start with a learner-paced lesson describing the different qualities of triangles and follow with a fun karaoke session. Also provided are two types of...

Triangles are classified by their angle measurement as well as by the length of their sides. Here are some names that identify the types of triangles: isosceles, equilateral, scalene, obtuse, and acute. Watch this video to learn about...
