### Similar Triangle Rocket Activity Sheet

by Zack Moore

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.
