Check Similarity In Right Triangles Calculator
Result
Compare corresponding leg ratios of two right triangles using a fixed numerical tolerance; enter both pairs in the same order.
Formula
- Enter the two positive leg lengths for each right triangle, pairing corresponding legs in the same order. The calculator compares the ratios a1/b1 and a2/b2 and returns Similar if the absolute difference is less than 1e−9. This simple check does not automatically match swapped legs, and invalid or zero legs can produce errors or misleading labels.
- The main inputs are Triangle1 leg a, Triangle1 leg b, Triangle2 leg a, Triangle2 leg b. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Check Similarity In Right Triangles
- Triangle1 leg a: 3
- Triangle1 leg b: 4
- Triangle2 leg a: 6
- Triangle2 leg b: 8
Using Triangle1 leg a = 3, Triangle1 leg b = 4, Triangle2 leg a = 6, Triangle2 leg b = 8, the calculated result is Similar.

Frequently asked questions
What does the Check Similarity In Right Triangles calculate?
Compare corresponding leg ratios of two right triangles using a fixed numerical tolerance; enter both pairs in the same order.
Which values should I enter?
Enter Triangle1 leg a, Triangle1 leg b, Triangle2 leg a, Triangle2 leg b using the units and format shown beside each field.
What formula does this calculator use?
The calculator uses the following relationship: For two RIGHT triangles with corresponding ordered legs a1, b1 and a2, b2, this tool compares r1 = a1/b1 to r2 = a2/b2 and reports Similar when |r1 − r2| < 10^(-9). All leg lengths must be positive and b1, b2 nonzero. This is an absolute ratio tolerance, not a scale-invariant tolerance. Interchanging leg order in one triangle can cause a false negative; zero inputs or extreme ratios are not robustly handled by the current motor..
Why might my result differ from another source?
Results can differ when another source uses different units, rounding rules, conventions or assumptions. Compare the inputs and definitions before comparing results.
Does the result update automatically?
Yes. Changing an input updates the result using the same calculation engine shown on this page.
