Answer:
The correct answer option is AAS.
Explanation:
We are given two triangles: ΔABC and ΔCBD and we are two figure out by which postulate can their congruence be proved.
We can see from the given diagram that angle A and angle B are equal to that of angle C and angle B respectively. Also, the non-included side of these two angles, side AD and CD, are equal here.
According to the Angle Angle Side postulate, two triangles are said to be congruent if two angles and the non-included side of one triangle are congruent to the two angles and the non-included side of another triangle.
