Question

check if a triangle with sides 10 cm , 6 cm and 8 cm is a right triangle​

Answer 1

Answer:

No it's not

because by the theorem , the sum of two small sides should be equal to the biggest side .

Hence , it's not a right angle traingle

Answer 2

According to the Pythagoras theorem, a²+b²=c²

Now, LHS = RHS

6² + 8² = 10²

LHS = 6² + 8²

= 36 + 64

= 100

RHS = 10²

= 100

LHS = RHS

Therefore, the given triangle is a right triangle.
