Checked 9801 combinations

Description:

a, b, c: sides of the triangle

max Δ(a,b,c): desired accuracy of dimensions

Δc: difference between calculated and approximated value of c

α: calculated value of angle α assuming exact dimensions

90°: calculated value of 90° angle assuming exact dimensions

max Δ90°: maximal error of 90° angle

D1(max Δ90°): unity distance at angle (max Δ90°), helps to better understand small angles size

For example enter 2 ≤ a ≤ 100, 2 ≤ b ≤ 100, and max Δ of 0.01. Suppose dimensions are in centimeters, so accuracy of 0.1mm is quite good. Sort by max Δ90° descending ↓

Look at the results. First result (3,4,5) is an Pitagorean triple, but due to dimension deviation of 0.1mm, the maximum 90° angle error is 0.2873°, that's a pretty big error. This can be visualised as 1 meter viewed form 200 meters (or 1 centimeter viewed form 200 cm).

Better results are for triples (6,8,10) and (5,12,13) → max error equals 0.1434°.

It is interesting that triples (10,49,50) and (10,50,51) which do not satisfy the equation a²+b²=c², gives smaller maximum angle error than next Pitagorean triples (9,12,15) and (8,15,17).

This is because of the bigger values of a, b and c in this case, so relative accuracy is better.

As you can see in the table, there are surprisingly many non-Pitagorean triples, which can nevertheless be used as the lengths of the right triangle sides.

In the length range 2-200 the best results are given by the Pythagorean triple (180,189,261), but the triple (189,197,273) is only slightly worse.

Of course, the 90° angle error decreases with increasing dimensions and increasing accuracy (smaller Δ).

Knowing the effects of dimensional errors, we can optimally select the lengths of the triangle sides according to the required accuracy.
