Help with Visual Basic (A triangle face)

[oleges]

Hello everyone i am really new at visual basic.In my school we are doing a project (windows form application)in which we have to find the face of a triangle.
Can anyone help me with the code.

You'd have to give a MUCH better description than that. For one thing, triangles don't really have faces, because they are two dimensional constructs. For another thing, finding a face is an inherently subjective/visual activity which is certainly not a simple task, so you were most definitely asked to do something a bit different from what you just described.

...For one thing, triangles don't really have faces, because they are two dimensional constructs...

True...but not always... There are 3D triangles called tetrahedrons - those are 3D objects whose faces are composed of triangles.
Perhaps OP is looking for one of those? But I agree - more detailed description will definitely help.

I thought a tetrahedron was a tetrahedron, and a triangle was always a 2D construct with three sides. Even in graphics, in which I have barely dabbled, this seems to be a common convention.

perhaps "face" was the wrong word and the OP meant the "area" depending on the type of triangle it is, seems mostly simple to do...

See Area of a triangle and follow the link there to Area of a Triangle by formula (Coordinate Geometry).

If you can't turn this into code you might need some tutoring.
