This vb Component for Grasshopper takes three edge length and produces the corresponding triangle.  This particular function begins with the first edge being aligned to the x axis of the world top in Rhino and produces the geometry so long as the three input numbers are valid to create a triangle. The component has been updated to work on a user specified plane.
INPUT Plane Item P Plane which defines the triangle. The origin and X axis of the plane set the origin and direction of edge A.
INPUT Double Item A The length of edge A
INPUT Double Item B The length of edge B
INPUT Double Item C The length of edge C
OUTPUT Mesh Item T Sorted list of points.
