Question

among the following measures which does not represents the sides of right triangle
a)9.12.15 b)3.4.5 c)2.1.root5 d)5.7.9​

Answer 1

Answer:

d) 5,7,9

It does not represent the sides of a right angled traingle.

Step-by-step explanation:

9 is the longest side so it is the hypotenuse of the triangle.

5 and 7 are base and perpendicular of the triangle respectively.

By Pythagoras Therom,

Base² + Perpendicular² = Hypotenuse²

5² + 7² = 9²

25 + 49 = 81

74 not equal to 81

Since, the Pythagoras Therom is not applicable in the given sides, therefore the right angled traingle with sides 5,7,9 is not possible.
