Answer: In triangel ABD and ACD angle A =angleA(AD is bisector of angleA) AD=AD(common) angle D=angleD(AD perpendicular BC) By ASA condtion ABD congruent to ACD By CPCT angle B=angleC Hence proved! Step-by-step explanation: Reply

Answer:In triangel ABD and ACD

angle A =angleA(AD is bisector of angleA)

AD=AD(common)

angle D=angleD(AD perpendicular BC)

By ASA condtion ABD congruent to ACD

By CPCT angle B=angleC

Hence proved!
