Question

In ∆ABC,AD⊥BC,∠B=∠C and AB=AC. State by which property ∆ADB is congruent to ∆ADC ?a) SAS b) SSS c) RHS d) ASA

Answer 1

Answer:

C) RHS ......is the correct answer.

Answer 2

Answer:

a) SAS

Step-by-step explanation:

Given

∠ADB=∠ADC(AD⊥BC)

∠B=∠C

AB=AC

To prove ∆ADB≅∆ADC

Proof

AD=AD(Common side)

∠ADB=∠ADC(given)

BD=BC(∴AD⊥BC)

∆ADB≅∆ADC(By SAS congruency)
