The 3 types of angles

Three letter-sized mini posters can be displayed in your elementary geometry class when teaching about angles. One provides information about degree measurement and additive properties, and the other two define acute, right, obtuse,...

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 intersecting lines,...

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...

How do you determine the size of an angle? Pupils learn about degrees and how to measure the size of an angle. The video associates the measurements to types of angles such as acute, obtuse, and right. The additive properties of angle...

Fourth and fifth graders identify three types of angles, recognize that angles are measured in degrees, measure angles using protractors or angle rulers. They classify angles as a class, classify angles on pattern blocks, and complete a...

How can geometry learners remember the difference between supplementary and complementary angles? Not only will the video explain how to remember these two angles, but it also demonstrates how to find unknown angles knowing the degree of...

Measuring angles is a mysterious task. What do those degrees mean? A clock is used to show what each angle looks like on a circle as the hands move around to mark time. The lesson explains that rays are just like the hands of a clock,...

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...

Fourth and fifth graders make a protractor and identify various angle types. In this protractor and angle lesson plan, learners make their own protractor and use it to measure a variety of angles. They complete worksheets while...
