Classify and Measure Angles

Classify and Measure Angles

Below you’ll find a variety of “Classify and Measure Angles Worksheets!” Understanding the differences between angles can be challenging, but we’re here to help!

Our worksheets will help your students measure and classify acute, obtuse, and right angles.

Understanding the differences between special angles is essential for success in Geometry. It prepares students for trigonometry and calculus and has applications in physics, engineering, and navigation.

All of our Worksheets are useable in a classroom or homeschool and include answer keys. Didn’t find what you were looking for? Check out our other Geometry worksheets!

Classify Angles (Printable PDFs)

In the classifying angles worksheets below, students will practice identifying angles as acute, obtuse, right or reflex. Right angles = 90°. Acute angles are less than 90° and obtuse angles are greater than 90° (but less than 180°). Reflex angles are greater than 180° (but less than 360°).

Measure Angles (Printable PDFs)

In the measuring angles worksheets below, students will use a protractor to measure each angle and then classify it as either acute, obtuse, right or reflex. Right angles = 90°. Acute angles are less than 90° and obtuse angles are greater than 90° (but less than 180°). Reflex angles are greater than 180° (but less than 360°).
