Do you mean RA and dec?

If the stars are close to one another you can use Pythagoras.
declination is already in actual degrees;
Right Ascension must be converted from hours to degrees,
(15 deg/hr) cos(dec) , to compensate for meeting at the pole.

If the stars are far apart, you'll have to make a great circle
that passes through them both.
