If `Delta ABC ` be an equilateral triangle and `AD _|_BC`, then `AD^(2)` =

If triangleABC is an equilateral triangle such that AD bot BC , then AD^2 =

Prove that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. Use the above theorem, in the following. If ABC is an equilateral triangle with AD bot BC , then prove that AD^(2) = 3DC^(2) .

In an equiliteral triangle ABC, if AD bot BC , then___

triangle ABC is an equilateral triangle and AD bot BC , where D lies in BC. If AD= 4 sqrt3 cm, then what is the perimeter (in cm) of triangle ABC ? त्रिभुज ABC एक समबाह त्रिभुज है तथा AD bot BC है, जहाँ D, BC पर स्थित है | यदि AD= 4 sqrt3 सेमी है, तो त्रिभुज ABC का परिमाप ( सेमी में) कितना होगा ?

In an equilateral triangle ABC, AD _|_ BC . Prove that : AB^(2) + CD^(2) = 5/4 AC^(2)

In an equilateral triangle ABC if AD_|_BC then AD^2 = a) CD^2 b) 2CD^2 c) 3CD^2 d) 4CD^2
