South Caro-angular

Three letter-sized mini posters can be displayed in your elementary geometry class when teaching about angles. One provides information about degree measurement and additive properties, and the other two define acute, right, obtuse,...

In this angles worksheet, students draw the angles described to them and then decide whether it is an acute, right, obtuse, or straight angle. Students complete 4 problems.

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...

In this classifying and measuring angles learning exercise, 10th graders solve and complete the measures of various types of angles. They determine whether each angle drawn is a straight, right, obtuse, acute, or reflex angle. Then,...

Learners sharpen their classification of angles skill with a simple angles worksheet that starts with unlabeled angles and ends with specific angle measures to classify.

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).

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...

This video lesson describes and provides examples of right, acute, and obtuse triangles. Students can check their understanding with an assessment. [2:24]

This video lesson shows examples of classifying triangles by their angle measurements. Students can check their understanding with an assessment. [3:54]

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