1. The problem states that triangle ABC is congruent to triangle XYZ. 2. By the definition of congruent triangles, corresponding angles and sides are equal. 3. Angle CAB in triangle ABC corresponds to the angle at vertex X in triangle XYZ because the order of letters in congruence statements matches corresponding vertices. 4. Therefore, angle CAB is congruent to angle ZXY. Final answer: Angle CAB is congruent to angle ZXY.
