CODING PRACTICE - 3 Valid Triangle

 Valid Triangle

Given three angles of a triangle, write a program to check whether the triangle is valid or not. A triangle is valid if the sum of its three angles is equal to 180 degrees.

---

Input

The first line of input will contain the first angle of the triangle.
The second line of input will contain the second angle of the triangle.
The third line of input will contain the third angle of the triangle.

---

Output

If the sum of the three angles is equal to 180, print "It's a Triangle". In all other cases, print "It's not a Triangle".

---

Explanation

For example, if the first angle is 80, the second angle is 90, and the third angle is 100. Therefore the sum of the three angles(80 + 90 + 100) is 270, which is not equal to 180. So the output should be "It's not a Triangle".
Similarly, if the first angle is 60, the second angle is 60, and the third angle is 60. Therefore the sum of the three angles(60 + 60 + 60) is 180, which is equal to 180. So the output should be "It's a Triangle".

Sample Input 1

80
90
100

Sample Output 1

It's not a Triangle

Sample Input 2

60
60
60

Sample Output 2

It's a Triangle 

Code:

a=int(input())
b=int(input())
c=int(input())
x=a+b+c

if x==180:
    print( "It's a Triangle")
else:
    print("It's not a Triangle")
