Answer 1

Answer:

no

Step-by-step explanation:

Answer 2

Answer:

39² = 15² + 36², So it is a right angled triangle​

Step-by-step explanation:

Given : Sides of a triangle a=15 cm, b=36cm and c = 39 cm

             we have to prove the triangle is right angled triangle

Solution : The right angled triangle follows pythogorous rule

It is Square of the biggest side = sum of squares of other two sides

∴  Here c² = a² + b² -----------1

Substituting the values of a,b and c in 1 , we get

        39² = 15² + 36²

LHS =    39²

       = 1521

RHS = 15² + 36²

        = 225 + 1296

        = 1521

∴ LHS = RHS

So it is a right angled triangle​
