## Inscribed Angle Calculation Formula

The formula for an inscribed angle is pretty straightforward: `Inscribed Angle = 1/2 * Central Angle`

. In this case, the central angle is the angle subtended at the center of the circle by the arc.

## Categories of Inscribed Angle Calculations

Category | Range | Interpretation |
---|---|---|

Small | 0° – 30° | Almost invisible to the naked eye |

Medium | 30° – 60° | Perfectly average |

Large | 60° – 90° | A sight to behold |

## Examples of Inscribed Angle Calculations

Name | Inscribed Angle | Central Angle | Calculation |
---|---|---|---|

Bob | 30° | 60° | 30° = 1/2 * 60° |

Alice | 45° | 90° | 45° = 1/2 * 90° |

## Ways to Calculate Inscribed Angle
