hey guys I found this App ( iTriangles ) it could help you with trigonometry, well it helped me, it has a triangle solver and a pdf with trigonometry topics :) hope you find it useful :)
thanks man, i understand how this works now... cos the stick is the same length as your arm, its as if the triangle with your arm and the stick (the smaller triangle) would be the same (scale wise) as the tree height and the distance on the floor...
i would imagine similarity of triangles has something to do with it.... hencematching up the length of the stick with the height of the tree from a suitably chosen distance d from the tree
ahhh... it's a right triangle, right,,,, ... lets see a level, a tape, perhaps a protactor... ahh, still watching..... slightly more accuate, though.. distance and angles should give slightly more accurate results than the "stick" method.. edited to add that if it's not level ground, you can still make two right triangles and hell trig works like a champ.... level ground and straight trees (preferably standing straight) work easier
Using those methods, it will only work on flat terrain, and you will be lucky if you're within 10 feet of actual tree height. And probably far less accurate if the tree has lots of branches or is a deciduous tree.

I remember learning this in Boy Scouts. Also, how to measure the width of a river using your hat. ;-)

I've tried this and it works, but why does it work? Anyone?

@hasimademselin
What bxs0099 said: Similar triangles. Base 1 is to base 2 as height 1 is to height 2, and base 1 equals height 1.
(base 1 = length of stick, base 2 = height of tree, height 1 = distance from eyes to stick, height 2 = distance from eyes to tree)
Draw a picture to help visualize.

Clever use of isosceles triangles. Genius to think of it in such a practical way.

Laser measurements are 99% accurate.

@rephaim22 That's why it's called an estimate,
