star - Triangular Asterism Trigonometry

Using the SIMBAD database for Alnitak, Saiph, and Sirius -- i.e.:



Alnitak: FK5 coord. (J2000): RA = 05 40 45.527 DEC = -01 56 33.26;
Saiph; FK5 coord. (J2000): RA = 05 47 45.389 DEC = -09 40 10.58;
Sirius; FK5 coord. (J2000): RA = 06 45 08.917 DEC = -16 42 58.02;



What is the trigonometric relationship in degrees -- length of sides and inclusive angles to four decimal places -- between these three stars when they are used to form a triangular aterism?
