Classifying Triangles Teacher Resources

In this geometry activity, students answer 8 fill in the blank questions where they must examine 5 different complex geometric figures to classify triangles.

In this math worksheet, young scholars analyze an informative chart about the measurement and angles of equilateral, isosceles and scalene triangles. Students then answer 5 questions about classifying triangles.

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

Through the examination of the relationship between the lengths of the sides of a triangles students will learn the classification of triangles (acute, right, or obtuse).

That's correct, it is right and scalene. The video introduces the two methods for classifying triangles, sides, and angles. A resource in the playlist for basic geometry provides the definitions for each of the classifications.

In this classifying triangles worksheet, students explore given lengths or angle measurements and then classify each triangle as isosceles, scalene or equilateral. They also determine if the triangle may be right, acute or obtuse. This...
