Answer 2

$\star\:\:\:\bf\large\underline\blue{Given:—}$

☛︎ AB = AC

☛︎ BD = DC

$\star\:\:\:\bf\large\underline\blue{To\: find:—}$

Angle ADB = ?

$\star\:\:\:\bf\large\underline\blue{Solution:—}$

In ∆ADB and ∆ADC

• AB = AC (Given)
• BD = DC (Given)
• AD Common

Therefore, ∆ ADB ~= ∆ ADC ...[By S-S-S property]

Angle ADB + Angle ADC = 180°

Angle ADB = Angle ADC = 90°

Therefore, angle ADB = 90°
