Don't be obtuse, this geometry unit is the just the right resource for educating the acute young minds in your class. From classifying and measuring angles, to determining the congruence of shapes, this...

For this measuring and classifying angles worksheet, 6th graders select the type of angle (acute, right, obtuse, straight) for 6 drawings, then use a protractor to measure each angle.

By using circles that they cut out and label themselves, learners literally "get a grip" on the angles they identify: supplementary, complementary, and vertical. They solve missing measurements based on properties of supplementary,...

Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...

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

Upper graders examine all angles. In this angle lesson, pupils practice measuring, drawing, and naming angles. They create posters regarding angle vocabulary.

In this angles worksheet, 7th graders review the definitions for a right angle, acute angle, obtuse angle, and straight angle. Students then use symbols to name each angle three different ways. Students classify each angle as acute,...

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. 

Your learners practice the foundations of measuring two-dimensional angles. As well as the explanation of how to measure angles and their classifications, learners have plenty of practice problems on this learning exercise.

In this classifying angles instructional 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...

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 arcs and central angles instructional activity, 10th graders solve and complete 25 different types of problems. First, they use the letters shown in the diagram to name each portion. Then, students find the measure of each arc or...

Students use a protractor to measure angles. They classify angles by type: right angle, acute angles, and obtuse angles. Students build and draw right, acute, and obtuse angles. They discuss how do people in various professions use...

Through the examination of the relationship between the lengths of the sides of a triangles students will learn the classification of triangles (acute, right, or obtuse).

In this classification of triangles activity, 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...

Practice angle estimation with a worksheet. First learners estimate three angles within 15 degrees, then they measure and name each angle. A reference website is given for additional activities.

Students draw and measure angles. In this angle measurement lesson plan, the teacher demonstrates how to form and measure angles while explaining the parts of an angle, then students practice.

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...

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

Junior geometers investigate the concepts of angles and turns using straws to perform a hands on activity. This is helpful for kinesthetic learners who have a hard time with mathematics. The lesson includes the dialogue to be used during...

For this angles worksheet, students solve 6 problems in which an angle is measured with a protractor. Students mark if the angle is acute, right, obtuse or straight.

In this classifying angles activity, 10th graders solve and complete 21 various types of problems. First, they use the diagram shown on the right to answer the questions that follow. Then, students solve for x and find the measure of...

Learners identify and create angles. In this angle measurement lesson, students use sticks to make models of angles, then measure and name each angle.

Learners identify names of angles. They use a large clock to demonstrate angles using certain times of day. Given a geoboard, students create figures with acute, right, and obtuse angles.
