If you're looking for a presentation to assist you in your teaching of triangles, this one could be for you. In it, learners are shown how triangles are classified by the size of their angles and by their sides. These are tricky concepts...

The four major types of angles, right, obtuse, acute, and straight are described in this fine presentation. First, the important vocabulary associated with angles is presented, then the types of angles are described. A protractor is...

Learners identify obtuse and acute angles in comparsion to a right angle. They identify obtuse, acute, and right angles. Pupils use "Shape Measure" to construct obtuse, acute, and right angles. They review line segements to locate right...

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.

Solve and complete 18 problems about angles. First,  demonstrate that each conjecture is false by giving a counterexample. Then write the inverse, contrapositive, and converse for the each statement. In addition, write 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...

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

Students 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.

Students classify angles. In this angles lesson, students explore the characteristics of angles, triangles, quadrilaterals and circles. They identify polygons and sing a classifying angles song. Students participate in a manipulative...

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...

In this intersecting planes worksheet, 10th graders solve and complete 27 various types of problems. First, they use the diagrams at the right to answer each of the questions. Then, students measure each angle shown and classify them as...

In this angles worksheet, learners identify angles as either being acute, obtuse, right, or straight. Students identify 4 angles.

In this angles practice worksheet, students respond to 4 questions that require them to identify the pictured angles as acute, right, or obtuse angles.

In this angle review instructional activity, students examine 4 angles and identify each of them as acute, right, obtuse, or straight angles.

In this angle measurement instructional activity, 10th graders solve 24 different problems related to determining the measurement of various angles. First, they define the various ways to measure an angle and define the type of angle...

For this angle measurement worksheet, 10th graders solve 24 problems that include determining the measurement of various angles. First, they define each angle and the specific type that is shown in each. Then, students determine the...

In this geometry worksheet, learners measure various angles. First, they write what type of angle each one is, whether right, acute, or obtuse. Then students estimate the measurement and then write the actual measurement for each angle.

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.

Pupils are introduced to some basic concepts of geometry. They explain that the definition of a triangle is a figure with three sides, three angles, and three points. Triangles can be named by using three points in their correct sequence.

In this finding unknown angles worksheet, 10th graders find each numbered angle's measure for 20 different angles shown in the diagrams. They calculate the size of an angle when the other two angles are known to equal 180 degrees. Then,...

Students measure, construct, and classify angles as acute, right, straight, and obtuse. Once they have completed an angle worksheet, students use a map of South Carolina to locate cities by constructing the aforementioned angles.

Sixth graders estimate the measurement of angles and then measure the exact distance using an angle ruler. In groups, they explore shapes and recognize the characteristics acute, obtuse and right angles. Students sketch required shapes,...

Third graders search for and locate examples of acute, right, straight and obtuse angles in the classroom. They record their findings by writing the exact location of each angle found and organize them into angle categories.

This activity from Shodor Education Foundation will help you learn or review your angle vocabulary.
