  1. The Circle Charlie Haffey Norwood Elementary Science

  2. A Circle Is…… • A type of line segment • One end joins the other (loop) • EVERY part of the line is the same distance from a single point • Single point is the center

  3. Definitions Center Circumference

  4. Lines Radius Diameter Tangent

  5. Dividing A Circle • One diameter • Two equal sections • Each section is ½ • AKA one half

  6. Dividing A Circle • Two diameters • Four equal sections • Each section is ¼ • AKA one fourth

  7. Dividing A Circle • 180 diameters • 360 equal sections • Each section is 1/360 • AKA one three hundred sixtieth • AKA one degree

  8. Here is an angle of 1 degree (1o) 1o

  9. 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
