Answer 1

Answer:

Let the side of an equilateral triangle be '2a' units .  

Then ,

Height of an equilateral triangle is given by  :

PT= Root 3/ 2 x(2a)= root 3a units

I think PT is perpendicular to QR .  

=> QT=TR= 'a' units

Since, we have    

      =>ST = a/3 units .

3) In right ΔPST ,

By Pythagoras Theorem ,

Hence Proved :
