Answer:
no it can't be sides of a right triangle
Step-by-step explanation:
let's take a triangle ABC
AB =1.2cm
BC=2 cm
AC=5cm
LETS TAKE "AC" AS HYPOTENUSE
AC²=5²
=25 -----(1)
AB²+BC²=(1.2)²+(2)²
=1.44+4
=5.44 ----(2)
(1) not = to (2)
it can be a right triangle only if it satisfies Pythagoras theorem
as the above sides does not satisfy Pythagoras theorem it is not a right triangle
