Properties of a circle

Properties of a circle. Full circle = 360⁰ Half circle (semi-circle) = 180⁰ Diameter = 2 (radius). Central Angles. Central Angle = Intercepted Arc. Angles ON the circle. Inscribed Angle = ½ Intercepted Arc. Angles IN the circle. Angle Formed I nside by Two Chords = ½ ( Arc + Arc) .

  1. Properties of a circle

  2. Full circle = 360⁰ Half circle (semi-circle) = 180⁰ Diameter = 2 (radius)

  3. Central Angles

  4. Central Angle = Intercepted Arc

  5. Angles ON the circle

  6. Inscribed Angle = ½ Intercepted Arc

  7. Angles IN the circle

  8. Angle Formed Inside by Two Chords =½ ( Arc + Arc) 

  9. Angles Formed OUTSIDE of the circle

  10. Angle = ½ (Lg Arc- Sm Arc)

  11. Angle formed by a tangent and a radius (diameter)

  12. 90⁰

  13. Length of Segments INSIDE the circle

  14. Part • part = Part • part c •d = a •b

  15. Length of Segments OUTSIDE the circle

  16. whole • outside = whole • outside
