θ = T L / K G

at the midpoint of each side

Where:

θ - angle of twist (radians)
T = Twisting or torque moment force-length, (in-lbs, N-mm)
L = Length (in, mm)
a = Distance as indicated (in, mm)
τ = Unit shear stress force / area (lbs/in², N/mm²)
G = Modulus of rigidity force / area (lbs/in², N/mm²)
K = Polar Moment of Inertia (in⁴, mm⁴) for section
