Degree

Subdivide the length around a circle into 360 arcs of equal length. A central angle for any of these arcs is called a one-degree angle.

of a circle = 1 degree

An angle that turns through n one-degree angles is said to have an angle measure of n degrees.

Protractor – What we use to measure angles

Some common angles

Classifying Angles by Degree Measure Zero angle is just a ray and measures 0° Straight angle is a line and measures 180° or

two distinct collinear rays that share a common end point. Acute angle is an angle that measures less than 90° Right angle is an angle that measures 90° Obtuse angle is an angle that measures more than 90°

and less than 180°

Sketch these in your notebook and write the type of each angle below it.
