Drawing a triangle within a square/rectangle

Let's say I have a rectangle shape. Inside that shape, I draw a triangle. I know the length of all the sides of that triangle. Is it possible to find out the length of the rectangle?

I know that I can find all the angles of using the Law of Cosines. After all this I end up with rectangle with 4 triangles inside of it.

I feel like I should be able to solve this problem.

Re: Drawing a triangle within a square/rectangle

what is the relation between sides of triangle and rectangle

Re: Drawing a triangle within a square/rectangle

No sides of the triangle share the same sides as the rectangle, so there are 4 separate triangles all together.

I know that it would be possible if one of the sides of the triangle was also the side of the rectangle, producing only three separate triangles.

The more I wrack my head around this, the more I think it's not possible.

Hello, triplell!

There is no unique rectangle.

No sides of the triangle share the same sides as the rectangle,

so there are *four* separate triangles all together.

From your description, one vertex of the triangle is a vertex of the rectangle.

Code:

` *-------*-------*`

| .*::* |

| .*:::::* |

|.*::::::::* |

*:::::::::::* |

| *::::::::* |

| *:::::* |

| *::*|

*---------------*

The triangle can be rotated slightly

and another rectangle can be circumscribed around it.

Code:

` *--------*----*`

| .*:::. |

| .*::::::* |

*::::::::::. |

| *::::::::* |

| *:::::::. |

| *:::::* |

| *::::.|

| *::*|

| *:|

*-------------*

There are an infinite number of such rectangles.
