Question

the lengths of the sides of a triangle are 9, 40, 41. state whether the triangle is right angled triangle awnser​

Answer 1

Answer:

this is right angled triangle

Answer 2

Answer:

It is a  right angled triangle

Explanation:

we all know that the bigger length is the hypotinuse of  the triangle .

so  

9 and 40 are the length of the side of the triangle

and  41 is the hypotinuse

to prove ,

we are using pythagoras theorem

9^2 +40^2 = 41^2

81+1600=1681

1681=1681

hence , 9,40 and 41 are the pythagorean triplet and

the triangle is right angled.
