The true statements from the option are
3. triangle ABC is congruent to triangle DCB by side-side-side postulate
4. Triangle ABC is congruent to triangle DCB by side-angle-side postulate.
Congruent triangles are triangles that that have equal angles and equal corresponding sides.
Triangle ABC is congruent to DCB
line BC = line BC ( reflexive property)
angle A = angle D ( given)
line AC = line BD ( given)
line AB = line CD ( given)
Therefore;
3. triangle ABC is congruent to triangle DCB by side-side-side postulate
4. Triangle ABC is congruent to triangle DCB by side-angle-side postulate.
