Question

the side of a angle are 5cm 12cm 13cm show that it is a right angled triangle

Answer 1

Solution :

Let a , b , c are sides of a triangle

ABC .

a = 5 cm , b = 12cm , c = 13 cm

Now ,

a² = 5² = 25

b² = 12² = 144,

c² = 13² = 169


169 = 25 + 144

c² = a² + b²

[ 5 , 12, 13 ] Phythogarian triplet ]

Therefore ,

a , b , c are sides of a right angled


triangle. [ By Phythogarian theorem ]

ABC is a right angled triangle .
