# Syntax

C# |

public double Angle( Plane plane ) |

Visual Basic (Declaration) |
---|

Public Function Angle ( _ plane As Plane _ ) As Double |

Visual C++ |
---|

public: double Angle( Plane^ plane ) |

#### Parameters

- plane
- Type: ceometric.VectorGeometry..::.Plane

A plane.

#### Return Value

Returns the intersection angle of the line and plane in [radian].# Remarks

If this is the acute or obtuse intersection angle depends on the orientation of the direction
vector of the line and the normal vector of the plane.

If this angle is 0, the line is parallel to the plane.

The intersection angle of a line and a plane is sometimes called dihedral angle.
