Once students understand angle basics, challenge them to find missing angles in this exercise!

Students get to practice measuring angles using built-in protractors in this fun geometry activity! After measuring, they'll put their angle knowledge to the test by classifying each angle as acute, obtuse, right, or straight.

Introduce your child to different angles starting with an obtuse angle and see him find the obtuse angles in this worksheet.

Put that protractor to good use! In this geometry worksheet your student will practice measuring each of these angles using a protractor.

In this excerpt from an upcoming math workbook, your junior detective will make a positive ID on obtuse, acute and right angles.

Learn some basic geometry with this worksheet all about the angle.
