Find out height of the Tree

There is a tree on the edge of bank of a river and you are standing on opposite side.

You have a 1 metre stick with you. How do you measure the height of tree without leaving your side (i.e. not crossing the river).

    You can determine the distance to the tree by marking off the base of an equilateral triangle with the tree as the peak. Then use similar triangles, with you at one vertex and the opposite side being either the tree or the meter stick. Using proportions it is easy to determine the height of the tree.
