Check if a Triangle is Valid Given Its Three Angles

Certification: Basic Level Accuracy: 45.28% Submissions: 106 Points: 5

Write a Python program that determines whether three given angles can form a valid triangle.

Example 1
    

  • Input: angles = [60, 60, 60]
    • 

  • Output: True
    • 

  • Explanation: 

      

    • Step 1: Check if all angles are greater than 0. Yes, all are 60 > 0.
      • 

    • Step 2: Check if the sum of angles equals 180. 60 + 60 + 60 = 180. Yes.
      • 

    • Step 3: Since both conditions are met, return True.
      • 

    

    •
Example 2
    

  • Input: angles = [90, 30, 0]
    • 

  • Output: False
    • 

  • Explanation: 

      

    • Step 1: Check if all angles are greater than 0. No, one angle is 0.
      • 

    • Step 2: Even though the sum 90 + 30 + 0 = 120 (≠ 180), we return False because one angle is 0.

Constraints
    

  • 0 ≤ angle ≤ 180

Solution Hints

    
  
  • Check if all angles are greater than 0
    • 
  
  • Verify the sum of angles equals exactly 180 degrees
    •

Steps to solve by this approach:

 Step 1: Check if all three angles are positive values.

 Step 2: Verify that all angles are greater than 0 degrees.

 Step 3: Calculate the sum of all three angles.

 Step 4: Check if the sum equals exactly 180 degrees (triangle angle sum property).

 Step 5: Return True if both conditions are met, False otherwise.
