The 2 statements that are true about the triangles are
Δ ADB ≅ Δ DCB by Side - Side - Side
Δ ADB ≅ Δ DCB by Side - Angle - Side
How to find the true statements
The true statements is knowing the congruence theorems.
The Side - Side - Side congruence theorem have that the 3 sides of the triangles being considered are congruent to each other.
Examining the figure we can see that the two sides are marked to be congruent. While the third side is congruent by reflexive property
The Side - Angle - Side congruence theorem have that the 2 sides and the included angle of the 2 triangles being considered are congruent to each other.
Examining the figure we can see that the two sides are marked to be congruent. As well as the included angles, are marked to be congruent.
