Triangle Inequality Theorem:
Where a, b, c are side lengths (meters, m)
From: | To: |
Definition: This calculator checks whether three given side lengths can form a valid triangle using the Triangle Inequality Theorem.
Purpose: It helps students, engineers, and designers verify if three lengths can form a triangle before proceeding with geometric calculations.
The calculator uses the Triangle Inequality Theorem:
Where:
Explanation: For three lengths to form a triangle, the sum of any two sides must be greater than the third side.
Details: Validating triangle sides prevents errors in construction, engineering designs, and geometric calculations where triangle properties are fundamental.
Tips: Enter three positive side lengths in meters. The calculator will verify if they satisfy all three inequalities of the Triangle Inequality Theorem.
Q1: What makes a triangle "unequal"?
A: An unequal triangle has all three sides of different lengths (scalene triangle).
Q2: Can this calculator be used for equal-sided triangles?
A: Yes, it works for all triangle types (scalene, isosceles, and equilateral).
Q3: What units should I use?
A: The calculator uses meters, but any consistent unit will work as long as all sides use the same unit.
Q4: What if one inequality fails?
A: The triangle is invalid if any one of the three inequalities fails.
Q5: Can this determine triangle type?
A: No, this only validates if a triangle is possible. Additional calculations would be needed to determine if it's acute, right, or obtuse.
