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...

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

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.

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.

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...

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...

Young mathematicians use this activity-based worksheet 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 up with...

In this geometry worksheet, 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

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.

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

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...

For this classification of triangles worksheet, 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 obtuse...

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...

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...

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. 

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 sorting angles worksheet, students distinguish the differences between right, obtuse and acute angles. Students determine what type of angle thirteen angles are as shown.

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,...

In this classifying angles activity, 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 determine...

Scholars explore triangles with rods of different lengths. Using rods of 2, 4, 6, 8, and 10 cm class members build as many different types of triangles as they can. They also describe properties of these triangles and determine...

In this geometry worksheet, students identify and draw right angles, acute angles, obtuse angles and straight angles. This one-page worksheet contains 34 problems.

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...

Make sure it is all right in class. Pupils review the Pythagorean Theorem and find sides of right triangles, either by simplifying radicals or using calculators to find approximate lengths. Learners find out how to use the converse to...
