The videos are short, to the point, and the quiz allows me to test their knowledge on whatever subject in social studies I am teaching at the time. I love the way expert tutors clearly explains the answers to my homework questions. An angle in standard position is said to lie in the quadrant where the terminal side resides. Those are the choices. The point you need to remember from all of this is that there are an infinite number of angles that are coterminal to any given angle. Explore over 4, video courses.

## CK12 Foundation

The angle formed by one complete counterclockwise rotation is assigned degree The radian measure of an angle is based on the length of an arc on the unit. In mathematics, the angle of rotation is a measurement of the amount, namely the angle, that a figure is rotated about a fixed point, often the center of a circle.

A clockwise rotation is considered a negative rotation, so that, for instance, a rotation of ° (counterclockwise) Angles are commonly measured in degreesradians, gons (gradians) and. The amount of rotation is called the angle of rotation and it is measured in degrees. You can use a protractor to measure the specified angle counterclockwise.
