How to measure the height of a tree

Here is how to measure the height of a tree if the tree is too tall for you to run a tape measure up. Do you measure the height of a tree, you can use simple geometry and create a triangle with a 90° angle and a 45° angle, and then look up the long side of the triangle at the tree, and wear your line of sight meet the tree, Measure the distance on the ground to the tree trunk, and that will tell you how tall the tree is. This works because the triangle with a 90° angle and 2 45° angles has two sides that are exactly the same length, the base and the height. That means that the distance on the ground to the bottom of the tree is the same as the distance from the ground to the top of the tree. This is a simple way to measure the height of a tall tree.
