Make the fish face right by moving only 3 matchsticks. Angles in a Circle Do Now: Get your notebook and something to write with. Then think about this while you wait for class to start… Make the fish face right by moving only 3 matchsticks. Solution

Find each in the picture: A tangent A secant A chord An inscribed angle A major arc A minor arc

Central Angle: angle with its vertex at the CENTER of the circle “outside” angles Picture: Memory Clue: Example: Central Angles 3

Inscribed Angle: angle with its vertex ON the circle (curved part) “outside” angles Picture: Memory Clue: Example: Inscribed Angles 4

“Inside” Angles: angles made by 2 chords “outside” angles Picture: Memory Clue: Example: Inside Angles

“Outside” Angles: angles made by 2 tangents, 2 secants, or 1 tangent and 1 secant Picture: Memory Clue: Example: Outside Angles
