Triangle validity

Write a program to check whether a triangle is valid or not, when the three angles of the triangle are the inputs. A triangle is valid if the sum of all the three angles is equal to 180 degrees.
        
       Input:-3 
40 40 100
45 45 90
180 1 1
       Input Description: The first line contains an integer T, the total number of testcases. Then T lines follow, each line contains three angles A, B and C, of the triangle separated by space. 
       Output: YES
YES
NO
       Output Description: For each test case, display 'YES' if the triangle is valid, and 'NO', if it is not, in a new line. 
       Constraints: 1 <= T <= 1000
1 <= A,B,C <= 180
