a=float(input('Enter the first angle: '))
b=float(input('Enter the second angle: '))

c=float(input('Enter the third angle: '))
if a+b+c==180:

print('Triangle is possible')
else:

print('Triangle not possible')

Output

Enter the first angle: 45
Enter the second angle: 90
Enter the third angle: 45
Triangle is possible

The elif Statement
The elif statement in Python stands for "else if". It is used to check multiple conditions in a program after the initial if
statement. If the first condition is not true, the program checks the condition specified by the elif statement. If that
condition is true, the corresponding block of code is executed.
