SAS, ∠A ≅ ∠C, AB ≅ CB , ∠ABD ≅ ∠CBD
.
Step-by-step explanation:
Given:
∠BDA ≅ ∠BDC
AD ≅ CD
TO Prove
ΔADB ≅ ΔCDB
Proof:
In ΔADB and ΔCDB
AD ≅ CD ....……….{Given}
∠BDA ≅ ∠BDC …………..{Given}
BD ≅ BD ....……….{Reflexive Property}
ΔADB ≅ ΔCDB ….{By Side-Angle-Side Congruence Postulate}
∴ ∠A ≅ ∠C ......{Corresponding Parts of Congruent Triangle are Congruent}
AB ≅ CB ......{Corresponding Parts of Congruent Triangle are Congruent}
∠ABD ≅ ∠CBD {Corresponding Parts of Congruent Triangle are Congruent}
Answer:
Option C is correct.
The expression represents the number of stamps Erykah has : 3r -6
Step-by-step explanation:
Let r be the number of stamps Chris has.
as per the given condition: Erykah has 6 less than 3 times the number of stamps in her collection that Chris has in his.
"3 times the number of stamps Chris has" means 3r
"6 less than 3 times number of stamps Chris has" which means subtract 6 from 3r i,e 3r -6
therefore, the expression 3r -6 represents the number of stamps Erykah has.
