Take a look at these angles: What kind are they? Give mathematicians practice identifying obtuse, acute, and right angles in this categorizing activity. Each type is pictured and explained at the top, and scholars examine nine sample...

Learners examine a figure made up of different types of triangles and then determine whether each triangle is right, acute, or obtuse. Next, they color each type of triangle a different color. Finally, pupils answer three fill in the...

In this classification of triangles learning exercise, 10th graders identify and complete 8 different problems that include determining the measurement and perimeter of various types of triangles. First, they color all right, acute, and...

In this geometry activity, students view ten angles of varying degrees and identify if the angle is acute or obtuse. The students write the answer on the lines provided.s

Start out with angles by asking your pupils to read this reading passage. Class members will learn about degrees, right angles, acute angles, and obtuse angles and then respond to five questions about the text.

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...

Have you ever wondered how circles and angles relate to each other? Read a passage about right angles, acute angles, and obtuse angles, and answer reading comprehension questions about the information you learn. 

Young mathematicians use this activity-based learning exercise to practice identifying various angles and triangles. The outline of the sheet allows for easy folding and cutting. When completely folded, the picture flap should match...

Get out those protractors! Once geometers can identify obtuse, acute, right, and straight angles, get them to measure and draw their own. There are six boxes here, each with an angle measurement. Learners use a protractor to draw the...

Learners name seven different angles in three different ways and then classify each angle as acute, obtuse, right or straight. They solve one word problem.

Upper graders solve ten multiple choice problems about angles and measuring angles.

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...

Four fabulous worksheets are included in this resource, all having to do with the measurement of angles. On the first, anglers will use a protractor to determine the degrees of 10 different angles. An arc is drawn on each. On the second,...

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...

Third graders create angle eaters where they use circles with cut outs to identify right, obtuse, and acute angles. Students complete 1 angle eater.

Learners first name angles in three ways, then classify them as acute, obtuse or right angles. Good practice when introducing the concept of different types of angles.

In this classifying angles learning exercise, 7th graders identify and complete 17 different angles illustrated on the sheet. First, they use the key given to outline each angle. Then, students use a protractor to measure each angle and...

Learners identify various angles and how to measure each type. They use a protractor to measure each of the angles. Students also write the name of the angle and identify the number of degrees for each.

Is it a line, line segment, ray, or angle? Identifying geometric figures is the focus. In addition to identification, learners recognize right angles or tell if an angle is less than or greater than a right angle. They tell if lines are...

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...

Learn how to measure acute, right, and obtuse angles with a protractor. After reviewing the way the protractor works, fourth graders measure nine angles on their own. For extra practice, have them measure different angles in their...

What a great introduction to the world of angles. See the different types of angles and their corresponding degree measurements. Use the provided assessment to test understanding with a variety of questions. 

Are these angles greater than, less than, or equal to a square corner? Using a visual guide, young geometers label 16 angles into one of these three categories. Use this before introducing the terms acute, obtuse, and right...
