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...

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.

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. 

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...

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

In this angles activity, students analyze a group of 8 angles. There are no directions for use, but students could measure these with a protractor or classify them as acute, right or obtuse.

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...

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...

Make a game of angle classification. Using the direction of the pool ball, scholars determine the measure of the created angles. They work to create and classify different types of angles throughout an engaging interactive.

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.

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...

Acute or obtuse? Seems right to me! As scholars explore the simulation, they investigate angle measures. Questions ask them to classify the angles using correct naming conventions.

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. 

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,...

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...

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...

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...

Angle ABC is not the same as angle BCA, but it is the same as angle CBA. Help your classes understand naming conventions of angles and, more importantly, the importance of naming angles correctly. Scholars practice the parts of the angle...

Practice important angle vocabulary using an interactive lesson. As learners manipulate vertical angles, they watch the supplementary and congruent angles adjust. Questions pertaining to vocabulary and measurements follow their exploration.

There's more to a quilt than just a pretty pattern—there's geometry! Explore angle classification using an artistic approach to show your class that quilt designs are really just intricate geometric patterns. Here, scholars create a...

Young mathematicians learn to see geometry from different angles with this simple printable resource. Providing multiple visual examples of angles, this simple document can be used as an instructional tool, a skills practice...

In this geometry worksheet, students identify angles using a word bank.  They differentiate between obtuse, acute or right angle.

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.
