Question

triangle ABC is isosceles with sides AB =AC and AD is altitude. if /_BAD is 50 then /_ ACD​

Answer 1

Given : AB = AC

Angle ADB = angle ADC (Both are right angles)

AD = AD (common)

So both the triangles are congruent

Therefore, BD = CD (CPCT)

Angle BAD = angle CAD (CPCT)

Hence AD bisec is both BC and angle A.
