  1. in each case, use law of cosines to get c or C:

    c^2 = a^2+b^2-2ab cosC

    Now, having all 3 sides, and angle C, use law of sines to get A and B:

    sinA/a = sinB/b = sinC/c

    In most geometry courses, we learn that there's no such thing as "SSA Congruence". That is, if we have triangles ABC and DEF such that AB = DE, BC = EF, and angle A = angle D, then we cannot deduce that ABC and DEF are congruent.
