Angles Resources
In geometry, an angle is formed by two rays or lines that share a common endpoint, called the vertex. Angles are measured in degrees or radians and describe the amount of rotation between the two sides. Common types of angles include acute angles (less than 90°), right angles (exactly 90°), obtuse angles (greater than 90° but less than 180°), straight angles (exactly 180°), reflex angles (greater than 180° but less than 360°), and full rotation (exactly 360°). Our geometry angles worksheets and resources help students practice identifying, measuring, and applying these angles in a variety of contexts.
Students can explore the parts of an angle, learn to distinguish positive and negative angles, and practice using angles in triangles, circles, and other shapes. Worksheets include exercises on determining angle measurements, recognizing angle types, and applying angles to solve real-world problems. By working through these activities, learners build confidence in understanding geometric principles and develop foundational skills for more advanced math courses such as algebra and calculus.
Designed for classroom and at-home learning, these resources cater to multiple learning styles, offering print and digital formats that make geometry accessible and engaging. Teachers, parents, and homeschoolers can use these worksheets to reinforce core concepts, provide extra practice, and support students as they progress from basic angle recognition to applying angles in complex mathematical problems. By mastering angles, students strengthen spatial reasoning, problem-solving abilities, and overall mathematical fluency.

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:
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.

- 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
