In an equilateral triangle ABC, If ADbotBC, B-D-C and AB = 12 cm, then the value of AD is

In an equilateral triangle ABC, If ADbotBC, B-D-C and AB = 12 cm, then the value of AD is

In triangle ABC, if AD perp BC and AD^(2)=BD*DC. Then find the angle BAC

In an equilateral triangle ABC, AD bot BC meeting BC in D then AD^2 =…………..

In an equilateral ABC,AD perp BC, prove that AD^(2)=3BD^(2)

In an equilateral triangle ABC of side 10cm, the side BC is trisected at D. Then the length (in cm) of AD is

In an equilateral triangle ABC, if AD perp BC, then 2AB^(2)=3AD^(2)( b) 4AB^(2)=3AD^(2) (c) 3AB^(2)=4AD^(2)( d ) 3AB^(2)=2AD^(2)
