In the realm of geometry, the Triangle Inequality Theorem stands as a cornerstone principle. It asserts that in any triangle, the sum of the lengths of any two sides must exceed the length of the remaining side. To bring this principle to life and make it easily applicable, the Triangle Inequality Theorem Calculator emerges as a handy tool. This digital assistant simplifies the process of determining whether three given lengths can indeed form a triangle.

Purpose and Functionality

The primary purpose of the Triangle Inequality Theorem Calculator is to assess the feasibility of forming a triangle with three given lengths. This assessment is not only crucial for educational purposes but also serves practical applications in fields such as architecture, engineering, and design.

How It Works:

  1. Input: The user inputs the lengths of three sides.
  2. Calculation: The calculator checks if the sum of any two sides is greater than the third side, based on the Triangle Inequality Theorem.
  3. Output: It then informs the user whether or not these sides can form a triangle.

Step-by-Step Examples

Example 1:

  • Input: 3a=3, 4b=4, 5c=5
  • Process: Check if 3+4>53+4>5, 3+5>43+5>4, 4+5>34+5>3
  • Output: Yes, these sides can form a triangle.

Example 2:

  • Input: 1a=1, 2b=2, 3c=3
  • Process: Check if 1+2>31+2>3, 1+3>21+3>2, 2+3>12+3>1
  • Output: No, these sides cannot form a triangle as one of the conditions fails.
