Common Angle Measures

Curated and Reviewed by Lesson Planet

Using a circle with clock like hands, the tutor explains common angle measurements. She shows that a full circular rotation equals 360 degrees, a quarter rotation equals 90 degrees, a three-quarters rotation equals 270 degrees, and a half rotation equals 180 degrees. She describes each angle in degrees and as they relate to pi. This is a great way to introduce what angles actually represent and where we see these angles in real life. A great way to teach angles!
