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...

In this classifying triangles learning exercise, 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...

Learn to use the Pythagorean Theorem with non-right triangles. Pupils use the interactive to discover the relationship between the lengths of sides for acute and obtuse triangles. They compare the squares of the sides of the triangles to...

Bring math and reading informational text together with a reading comprehension lesson. After kids read about isosceles, scalene, and equilateral triangles, they answer five comprehension questions to demonstrate how they can use context...

After reviewing characteristics of seven types of triangles, young geometers discover how to find the missing angle of a triangle. Then, they practice identifying triangles, find missing angles, and find missing side lengths of...

In this classifying triangles activity, 10th graders solve 12 different problems that include classifying various types of triangles. They classify and then identify each of the given triangles as isosceles, scalene, or equilateral....

Under which conditions can a triangle be classified as isosceles? High schoolers practice identifying isosceles triangles and special line segments, including angle bisectors, medians of triangles, and perpendicular bisectors of sides of...

In this classify the triangle learning exercise, students solve 6 short answer problems. Students identify the type of triangle being described according to its angle measures and side lengths.

Middle and high schoolers solve and complete 29 various types of problems. First, they match each name with its correct formula. Then, learners find the length of the missing side and the distance between the two points given. In...

In thins triangles review worksheet, students examine 4 triangles and their measurements. Students classify them as equilateral, isosceles, or scalene.

In thins triangles review worksheet, students examine 3 triangles and their measurements. Students classify them as acute, right, obtuse, equilateral, isosceles, or scalene.

In this triangles learning exercise, students identify 3 triangles by the length of their sides and 3 triangles according to their internal angles.

Polly want a polygon? Young mathematicians sort shapes using an interactive. They classify the shapes as convex polygons, concave polygons, or not polygons.

In this polygon activity, students observe pictures of polygons and identify their proper name. They read descriptions of polygons and determine the polygon described. This one-page activity contains ten problems.

In this geometry worksheet, 10th graders examine the special segments that occur in a triangle.  The three page worksheet contains twenty-five problems.  Answers are not included. 

More than a worksheet, learners go through geometry topics example by example on the nicely organized handout. From postulates to classifying angles, there are rules and examples provided for each topic. The ten pages of problems...

In this geometry worksheet, 10th graders determine if a polygon is convex or concave and apply the polygon Angle sum theorem and the polygon exterior angle sum theorem to determine the measures of interior and exterior angles of a...

In this geometry worksheet, 10th graders solve a  problem involving the possible lengths for the third side of a triangle given two sides and determine where the point of concurrency lies in relation to the triangle. The one page...

Are your geometry whizzes learning about angles and shapes? This online worksheet gives 10 multiple choice questions based on images and word problems. Concepts include deducting angle degree, classifying shapes, and identifying angle...

Have your class review how to identify right angles. Learners identify right angles, and then write the number of angles found in each shape.

After completing the lesson on classifying triangles, you can sing along with karaoke and test your knowledge.

This comprehensive web lesson describes how to classify triangles by their angle and side measurements. It provides real-world examples and exercises for students to practice the skill.
