Question

AD is an altitude of isosceles triangle ABC , then ∆ABD ≅ ∆ACD by


ASA

RHS

SAS

All of above​

Answer 1

Step-by-step explanation:

This is your answer for the question you asked.The last one is rhs test

Answer 2

Answer:

Given: AB= AC, <ADB and <ADC = 90⁰

ASA: <B = <C (Side are equal so angle are also equal)

AD=AD (Common)

<ADB=<ADC (Given)

Hence proved that they are congruent by ASA.

RHS: <ADB=<ADC (Given)

AB=AC ( Given)

AD=AD (Common)

Hence proved that they are congruent by RHS

SAS: BD=CD (Angles are equal so, side is also equal)

<ADB=<ADC (Given)

AD=AD(Common)

Hence proved that they are congruent by SAS

So, All of the above is the correct answer.
