Using Curve Desk

Enter two knowns: R or Δ plus one of T, L, C or E, or L with C.
Press Enter or Solve. Every other element fills in.
Add a third known to check it against the solved curve.

Angle input

When values disagree

If you enter more than two knowns and they conflict, Curve Desk warns you and names the value that disagrees.

Sketch

Drawn to scale from the solved curve: PC, PI and PT with the tangents T, the arc L in redline and the chord C dashed. PI and tangents are left off when Δ is 180° or more, or the PI falls off the sheet.

Units

Lengths can be in any one unit. Degree of curve is per 100 units of that length.
