### 6. Angles from Directions

Examples of computing angles from directions were covered in the **VI. Directions** topic. When a loop traverse is involved and all its angles are computed, the angle condition should be verified as a math check (*always* include a math check were possible).

Recall that the angle conditions for loop traverses are:

Angle type |
Condition |

Interior | |

Deflection - Even crossings | |

Deflection - Odd crossings |

If the condition is not met, then a math error exists. Go back over your comps.
