    Spherical Triangle

    Equation

    cos(c) = cos(a) cos(b) + sin(a) sin(b) cos(γ) | γ | angle opposite third side a | first side angular length b | second side angular length c | third side angular length

    Input values

    first side angular length | π/2 radians second side angular length | π/2 radians third side angular length | π/2 radians

    Result

    angle opposite third side | 1.571 radians = 0.001571 krad (kiloradians) = 90° (degrees)
