James and Chris each draw a triangle with one side 10 cm, one angle 45°, and one angle says their triangles are congruent. Why is this incorrect?

a) Side-Angle-Side (SAS) congruence is not applicable here.
b) The triangles may not have the same third angle.
c) They need more information to determine congruence.
d) All triangles with a side of 10 cm and one angle of 45° are congruent.
