In this measuring angles worksheet, students solve 10 problems in which angles are measured with a protractor and labeled with: acute, obtuse, right.

Sixth graders investigate different types of angles. For this geometry lesson, 6th graders use a protractor to identify acute, obtuse, and straight angles.

In this angles worksheet, students name and measure six angles.  Students then draw four angles with a protractor given the degree measure.

In this classifying triangles worksheet, 6th graders write the type of triangle, acute, right or obtuse, for 9 pictures of triangles, answers included.

In this triangles worksheet, students measure and calculate the measurements of eight triangles, their sums and classify the triangles as acute, obtuse or right.

Young scholars explore symmetry.  In this geometry and scientific inquiry lesson, students design paper airplanes with middle line symmetry, as well as right, obtuse, and acute angles.  Young scholars measure the plane's angles...

This presentation shows how triangles are classified by angle measurement and length of sides.  It reviews isosceles, scalene, obtuse, right, and acute classifications and includes questions for students to classify some of the...

Learners explore the concept of angles by interacting with numerous types of measurements. They create index cards with different angles. Then they pass the cards around to other students for comparison and measurement. They practice the...

In this triangles practice learning exercise, students respond to 4 questions that require them to identify the pictured triangles as acute, right, or obtuse triangles.

Students utilize their handheld and the Angles program to create a non-objective artwork. Images created by famous artists who have utilized angles in their art work are examined.

Students draw a chart (included in the lesson plan) to use with their investigation. They review terminology of triangles and receive toothpicks to use in the lesson plan. Beginning with three toothpicks, students form a triangle. They...
