## Methods

### GetOpposedSideFrom(triangleSide, angle, value)

#### Definition

Gets the length of the opposed side of a specific angle, from the length of either the hypotenuse or the adjacent side of the angle.

#### Arguments

Type | Name | Meaning |
---|---|---|

`TriangleSides` | `triangleSide` | The side of the triangle. |

`double` | `angle` | The value of the angle. |

`double` | `value` | The length of the chosen side. |

WARNING

If `triangleSide`

is equal to `TriangleSides.Opposed`

, an `Exception`

will be thrown.

#### Usage

```
using PeyrSharp.Core.Maths;
using PeyrSharp.Enums;
double opposed = Trigonometry.GetOpposedSideFrom(TriangleSides.Adjacent, 1.05, 5);
// opposed = 8.716576549915851
```

```
using PeyrSharp.Core.Maths;
using PeyrSharp.Enums;
double opposed = Trigonometry.GetOpposedSideFrom(TriangleSides.Adjacent, 1.05, 5);
// opposed = 8.716576549915851
```

### GetAdjacentSideFrom(triangleSide, angle, value)

#### Definition

Gets the length of the adjacent side of a specific angle, from the length of either the hypotenuse or the opposed side of the angle.

#### Arguments

Type | Name | Meaning |
---|---|---|

`TriangleSides` | `triangleSide` | The side of the triangle. |

`double` | `angle` | The value of the angle. |

`double` | `value` | The length of the chosen side. |

WARNING

If `triangleSide`

is equal to `TriangleSides.Adjacent`

, an `Exception`

will be thrown.

#### Usage

```
using PeyrSharp.Core.Maths;
using PeyrSharp.Enums;
double adjacent = Trigonometry.GetAdjacentSideFrom(TriangleSides.Opposed, 1.05, 8.71);
// adjacent = 4.996227561429541
```

```
using PeyrSharp.Core.Maths;
using PeyrSharp.Enums;
double adjacent = Trigonometry.GetAdjacentSideFrom(TriangleSides.Opposed, 1.05, 8.71);
// adjacent = 4.996227561429541
```

### GetHypotenuseFrom(triangleSide, angle, value)

#### Definition

Gets the length of the hypotenuse, from the length of either the adjacent side or the opposed side of a specific angle.

#### Arguments

Type | Name | Meaning |
---|---|---|

`TriangleSides` | `triangleSide` | The side of the triangle. |

`double` | `angle` | The value of the angle. |

`double` | `value` | The length of the chosen side. |

WARNING

If `triangleSide`

is equal to `TriangleSides.Hypotenuse`

, an `Exception`

will be thrown.

#### Usage

```
using PeyrSharp.Core.Maths;
using PeyrSharp.Enums;
double hypotenuse = Trigonometry.GetHypotenuseFrom(TriangleSides.Opposed, 1.05, 8.71);
// hypotenuse = 10.041234478169912
```

```
using PeyrSharp.Core.Maths;
using PeyrSharp.Enums;
double hypotenuse = Trigonometry.GetHypotenuseFrom(TriangleSides.Opposed, 1.05, 8.71);
// hypotenuse = 10.041234478169912
