What Triangle Inequality Theorem Calculator does
The Triangle Inequality Theorem Calculator on Omni Calculator determines whether three given line segments can form a triangle. Users input the lengths of the three sides, and the tool applies the theorem's rule that the sum of any two sides must be greater than the length of the remaining side, returning a clear yes or no result. The site provides the mathematical rule alongside a brief explanation of its geometric significance, noting that triangles are the simplest polygons and that this theorem is the essential step before analyzing angles or other properties. The calculator is part of a larger collection of triangle-related tools on the same domain, offering users a gateway to related calculators for area, angles, and other triangle metrics without leaving the site.

Triangle Inequality Theorem Calculator FAQ
- What is the triangle inequality theorem?
- The triangle inequality theorem states that for any triangle, the sum of the lengths of any two sides must be greater than the length of the remaining side. If this condition is not met, the three line segments cannot form a triangle.
- Can any three positive numbers be side lengths of a triangle?
- No. For three positive numbers to be side lengths of a triangle, they must satisfy all three inequalities: a + b > c, a + c > b, and b + c > a. If any one of these fails, a triangle cannot be formed.
- What happens if the sum of two sides equals the third side?
- If the sum of two sides equals the third side, the result is a degenerate triangle with collinear vertices and zero area, which the calculator typically treats as not forming a valid triangle.
- Does the order of entering side lengths matter?
- No. The calculator checks all three combinations (a + b > c, a + c > b, and b + c > a), so the order in which the three side lengths are entered does not affect the result.
