Question

In the given figure, if AB = AC and D is the midpoint of BC, then triangle ADB is congruent to triangle ADC by congruency.

• A. SAS
• B. ASA
• C. RHS
• D. SSS

Answer 1

The correct option is D SSS

In $△ABD$ and $△ACD$

(i) AB = AC .........(given)

(ii) BD = CD .........(D is midpoint of BC)

(iii) AD = AD ..........(common side)

$\therefore △ABD\cong △ACD$
(SSS congruency)
