Formula and methodology
Formula: Scale ratios are kₐ=a₂/a₁ and kᵦ=b₂/b₁; the reported difference is |kₐ−kᵦ|/max(kₐ,kᵦ)×100.
For right triangles, proportional corresponding legs are a direct numerical similarity check; the tolerance makes measurement rounding explicit.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Triangle 1 leg A — minimum 1.0E-6; maximum 1000000
- Triangle 1 leg B — minimum 1.0E-6; maximum 1000000
- Triangle 2 leg A — minimum 1.0E-6; maximum 1000000
- Triangle 2 leg B — minimum 1.0E-6; maximum 1000000
- Allowed ratio difference — %; minimum 0; maximum 100
Worked example
| Input | Value |
|---|---|
| Triangle 1 leg A | 3 |
| Triangle 1 leg B | 4 |
| Triangle 2 leg A | 6 |
| Triangle 2 leg B | 8 |
| Allowed ratio difference | 0.001 |
Both scale ratios are 2; ratio difference = 0%; triangles pass the tolerance check.
Assumptions and limits
- The selected legs are corresponding and positive.
- The test treats the supplied tolerance as a measurement allowance, not an exact proof from rounded data.
- A right angle is assumed by the input design; this page does not independently verify all three side lengths.
