Question

which of the following triplets will not form a right angled triangle?
a)10
b)2/5
c)5/2
d)1/3​

Answer 1

Answer:

Thus, (40, 20, 30) does not form a Pythagorean triplet. Hence, the given triangle with sides 40, 20 and 30 is not a right-angled triangle

We now that, sum of angles of triangle is equal to 180o. So, these triplets cannot be the angles of a triangle.

41^2. =>42^2 not equal to 41^2. Therefore the given triplet does not follow the Pythagoras theorem. Therefore it does not forms a right angled triangle.
