Answer» ong>Step-by-step explanation: It is given that triangle ABC is an euilateral triangle so AB=BC=AC and D is a point on BC such that AD perpendicular to BC. Now, Triangle ADB congruent to triangle ADC. so,BD=DC Therefore,BD=1/2 BC Now,prove it (that I have PROVED) Hope it will help you in every WAY.

ong>Step-by-step explanation:

It is given that triangle ABC is an euilateral triangle so AB=BC=AC and D is a point on BC

such that AD perpendicular to BC.

Now,

Triangle ADB congruent to triangle ADC.

so,BD=DC

Therefore,BD=1/2 BC

Now,prove it (that I have PROVED)

Hope it will help you in every WAY.
