How to calculate the angles and sides of a triangle?
A triangle is determined by 3 of the 6 free values, with at least one side. Fill in 3 of the 6 fields, with at least one side, and press the 'Calculate' button. (Note: if more than 3 fields are filled, only a third used to determine the triangle, the others are (eventualy) overwritten
- 3 sides
- 2 sides en 1 angle
- 1 side en 2 angles
For a triangle, following rules are always true:
- the sum of the 3 angles is excactly 180 degrees (or pi radians)
- the sum of two sides is always bigger than the third side
