Triangle Analyzer

Analyze triangle validity, perimeter, area, angles, and type.

Triangle Analyzer computes perimeter, area, and triangle type from three side lengths. Use it to check side-validity, classify triangles, and summarize basic geometry from one set of side inputs.

Input guidance

Enter side a, side b, and side c.

How to use this tool

Enter side a, side b, and side c.
Run the analyzer.
Review whether the sides form a valid triangle, plus perimeter, area, and type.

Triangle Inputs

Result

Perimeter: 12.000000

Area: 6.000000

Angles: 36.8699°, 53.1301°, 90.0000°

Types: Scalene and Right

Formula or method

All three side lengths are constrained to zero or greater before validation.
A triangle is valid only when each side is positive and each pair of sides sums to more than the third side.
Perimeter is the sum of the three sides, and area is calculated with Heron's formula.
Angles are calculated with the law of cosines, then converted from radians to degrees.
Side type is based on rounded side equality, and angle type is based on the largest angle.

How to interpret the result

Check units, model assumptions, rounding, and whether the formula matches the scenario before relying on the result.

Confidence and limitations

Outputs are deterministic formula results and depend entirely on input quality and units.
Results are for planning and learning; verify with domain standards before safety-critical use.
Rounding and finite precision can introduce small differences in edge cases.
