Analysis in triangles

Check the ‘Analysis in triangles’ box if you wish the calculation and analysis of the surface area to be carried out using triangles only. If you leave it unchecked, then rectangular, trapezoid, triangular and curved shapes will be used for the analysis (See Measurement analysis ).

If the area to be calculated includes curved parts then the analysis is always carried out by the second method, even if you check the ‘Analysis in triangles’ box.

Analysis using only triangles is useful for on-site measurements. Calculations are performed using the Heron’s formula:

$T={\ \sqrt{(a+b+c)(-a+b+c)(a-b+c)(a+b-c)\ \over 16}\,}$
