Use the given information to prove that triangles ABC and CDB are congruent. Explain your reasoning.

Triangles ABD and DCB are right triangles​ (a)   AB, BC CD and DA​ (b)   AB=AB​ (c)   . So, triangle ABD and CDB are congruent by ​ ​ (d)  

​​

​ ​

• because ABCD is a square

• are congruent because ABCD is a square

• because reflexive property

• HL

• AAA

• Opposite angles are congruent
