#### Trigonometry is the branch of math that (as the name indicates) focuses on the relationships and sides of triangles. While you might think that the study of a single shape would have a very narrow scope of application. Trigonometry was historically used in astronomy and geography mostly for its navigation and wayward applications. The physics and engineering applications of trig are boundless. Just about every modern structure on the planet was developed and constructed using many of the root principles of trigonometry. Trig is the fundamental math used by astronomers to measure the distances between planets and stars. Architect use this form of math to design the plan for any home or building that they design. It insures the strength of many modern structures. The geometric shapes that are displayed in most forms of architecture are constructed in that way to ensure maximum reliability of the structure, regardless of where you are located within it.

We will start of by showing you how to make these forms of calculation and we will then progress on to helping you learn how to better choices based on these calculations. The ultimate goal is to help students to learn to evaluate and measure systems with the data that is presented to them. This will be a very profound skill to have in the real world. You will find worksheets that include arithmetic of triangles, comparisons, understandings of variation, the use of coordinate grids, Pythagorean properties, trig identities and sequences.
