2 Angle Specifics Angles constructed from a Counter-Clockwise rotation are said to be ________________, where as angles that open Clockwise are said to be ___________________. Angles which have different amounts of rotation but the same initial and terminal sides are called _________________. Slide: 3of 14 is 0 More Angle Specifics A zero angle represents “not rotating a ray”, and therefore its terminal side is the __________ as its initial side. The positive x-axis and positive y-axis are rays which join together at the origin . The angle which rotates the positive x-axis to the positive y-axis is known as a ______________ angle. Slide: 4of 14 is 0

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
