If you mean the use of similar triangles and the similarity of the linear dimensions of the shadows to calculate the linear dimensions of any object which can not be measured directly you need one indispensable condition to solve this problem.
This condition is the need for a parallel lines (such as directions to practically infinitely distant star) or lines which we can assume that in parallel with the permissible error of proportion (such as rays of the sun), Otherwise, if this condition is not feasible then due to parallax effects, the results of the calculations will be not reliable.
If this condition (the presence of parallel lines) is satisfied then we can measure with reasonable accuracy the length of the elements of imaginary triangles and applying one of the Thales theorems, to make a proportion and calculate the required interval (distance or height).
What else can I help you with?
What do you call two triangles with proportional sides?
They are said to be similar but not congruent triangles.
What is the term used for the Triangles whose corresponding angles are equal?
They are similar triangles.
Triangles ABC and DEF are similar. Find the length of segment EF.?
To find the length of segment EF in similar triangles ABC and DEF, you need to use the properties of similar triangles, which state that corresponding sides are proportional. First, identify the lengths of corresponding sides from both triangles. Then, set up a proportion using these lengths and solve for EF. If you provide the lengths of the sides, I can help you calculate EF specifically.
Two equilateral triangles are sometimes similar?
Two equilateral triangles are always similar!
How do the ratios of side lenghts compare for triangles that are not similar?
There are no ratios that can be used for triangles that are not similar.
Find the measure of s if these triangles are similar?

Is sss a way to find if triangles are similar?
Triangles are congruent if all three sides in one triangle are congruent to the corresponding sides in the other.When two triangles have corresponding sides with identical ratios, the triangles are similar.Of course if triangles are congruent, they are also similar.

Which pair of triangles must be similar?
Pairs of triangles, in general, do not have to be similar.

How do you find out if two triangles are similar?
you measure both of their angles and see if they are the same i think.

There are no ratios that can be used for triangles that are not similar.
Why are triangles similar?
why triangle are similar
Are two obtuse triangles always similar?
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
How man triangles can be isosceles and have an angle of 65 degrees?
Infinitely many. Having found one triangle, you can find infinitely many similar triangles.
