Classifying Angles Resources

Angles might not be all right, but these resources on classifying angles will make them alright for students! Worksheets introduce the concepts of right, acute, and obtuse angles, and provide students with practice classifying angles. Lesson plans include hands-on activities to help students improve their geometry skills in a fun way. For more angle exercises, review our measuring angles resources.
When students are first introduced to geometry, they’ll realize they see angles everywhere. Whenever two lines meet, they form an angle. Angles are present in all two-dimensional and three dimensional shapes whenever two sides or edges meet. Depending on their measurement, they can also be categorized.
And angle is comprised of three pieces; two lines and a vertex where the lines meet. Because the angle is viewed as and measured as an arc, the unit we use for measuring an angle is a degree. A full rotation would be 360 degrees. Angles fall into at least one of five main categories:
  • Straight Angles - Straight angles are those where the two lines are parallel and could constitute a single line. The measure of a straight angle is always 180 degrees and would perfectly bisect the full circle of the arc.
  • Right Angles - A right angle occurs when the two lines that constitute the angle are perpendicular to each other. This results in a 90 degree angle that would represent one quarter of the full arc.
  • Obtuse Angles - Obtuse angles are any angle whose measure is greater than 90 degrees and less than 180 degrees.
  • Acute Angles - When an angle’s measure is less than 90 degrees, it is called an acute angle.
  • Reflex Angles - When an angle is larger than 180 degrees but still less than a full 360 degree rotation, it is called a reflex angle.

Working with students on measuring and categorizing angles using the resources provided by Education.com above may help them not only understand angles but also give them a greater geometrical sense overall.
