This activity sheet explains rocket triangulation. The objective is to use your knowledge of similar triangles to determine the total vertical height covered by a soda bottle rocket in flight. We will also use our understanding of trigonometry to double-check the total vertical height. The file is saved as a Word 1997-2004 .doc document.
