Else statement V (need explaination/hint instead of solution)

Question

side1 = int(input())
side2 = int(input())
side3 = int(input())
#your code goes here
if(side1 and side2 and side3)>0:

if (side1 ==(side2+side3) or side2==(side1+side3) or side3==(side1+side2)):
print("Not right-angled ")
else:
print("Right-angled ")

Answer 1

side1 = int(input())
side2 = int(input())
side3 = int(input())
if side3**2 == side1**2 + side2**2:
print("Right-angled")
else:
print("Not right-angled")
