Angle Resources

Angles are an important concept in geometry and are used when working with shapes like circles and triangles. Once your child has mastered using angles, they are ready to start moving on to a higher level math subject, such as algebra. Help your student learn how to work with angles by looking at our different resources, or if your child is ready to move ahead, see how angles are used in triangles.

A Guide to Angles

Angles are used to measure how far something has turned. Below is a guide for getting started with angles.

Parts of an Angle
An angle is made up of two lines called arms. These arms are connected at one end to form a point called the vertex. The angle is then defined to be the amount of turn between each arm.

Types of Angles
Different angles have different names depending on their angle:
  • Acute: an angle that is less than 90 degrees
  • Right: an angle that is exactly 90 degrees
  • Obtuse: an angle that is greater than 90 degrees but less than 180 degrees
  • Straight: an angle that is exactly 180 degrees
  • Reflex: and angle that is greater than 180 degrees
When working with angles, there is also a difference between a positive and negative angle. A positive angle rotates counterclockwise, while a negative angle rotates clockwise.

In more complex math classes, students begin to learn how to determine if angles are congruent, or equal, and how to use angles in math classes like algebra and calculus. To help your student start their journey through angles, check the resources on this page, or move over to our geometry page to learn more about how angles are used in shapes.
