Lines Radius Diameter Tangent
Dividing A Circle • One diameter • Two equal sections • Each section is ½ • AKA one half
Dividing A Circle • Two diameters • Four equal sections • Each section is ¼ • AKA one fourth
Dividing A Circle • 180 diameters • 360 equal sections • Each section is 1/360 • AKA one three hundred sixtieth • AKA one degree
360 degrees (360o) • End of diameters shown • Degrees labeled by 10s • Every degree marked Circular Protractor http://xt8dob.files.wordpress.com/2012/05/degree-wheel.png
