What does a geometric farmer drive? A protractor, of course! A set of assessment worksheets prompts learners to use a protractor as they measure angles, name angles, and identify lines. Use the video as a way to...

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...

Why was the obtuse angle upset? Because it was never right! A valuable resource is loaded with background information on types of angles and lines. Learners review the characteristics of parallel, perpendicular, and...

Sixth graders identify and measure right, acute, obtuse, and straight angles. In this geometry lesson, 6th graders review the definition of each angle and are shown examples of each specific angle. Students use toothpicks, gumdrops, and...

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

Students find triangular angles using the angle theorem. In this geometry instructional activity, students describe labeled triangles, use the pythagorean theorem, and rewrite information about triangles in standard form.

Eighth graders identify and compare acute, right, obtuse, and straight angles. They draw two angles on pieces of construction paper so they can accurately know what it looks like. Students hang the drawings on the wall. They are asked...

Third graders analyze angles and determine if they are acute, right, or obtuse. In this angles lesson, 3rd graders study the definition and characteristics of each angle. Students then do a worksheet to identify the name of the angle.
