5) In the given figure AB = AC and AD is the bisector of (a) Is give reasons.
(a) AB = AC ( Given )
∠ BAD= ∠ CAD ( DA is bisector of ∠ BAC)
AD=AD (common)
Hence, Triangle ADB congurent to ADC(by SAS congurency rule)
(b) ∠B = ∠C (By CPCT)
∠ BAD= ∠ CAD ( DA is bisector of ∠ BAC)
AD=AD (common)
Hence, Triangle ADB congurent to ADC(by SAS congurency rule)
(b) ∠B = ∠C (By CPCT)
