Algebraic Connections Std 7: Determine missing information in an application-based situation by using the properties of right triangles, including trigonometric ratios. Example: application—construction or landscaping problem

Lesson Plans Chicago Public Schools This is a collection of daily lesson plans on the Pythagorean theorem. It goes from geometric mean to trigonometry. The Noon Project Revisited Shadow measurements to determine the circumference of the Earth. Build a Clinometer Students will construct an angle-measuring device called a clinometer (sect 3), and will use it to measure the Angle of Elevation of several inaccessible objects outside of the school. Sequencing Segments In this lesson, students use trigonometric ratios to see the complexities of air traffic control.

Resources: Introduction to Trigonometry An introduction to right triangle trigonometry. Includes an interactive triangle which allows the student to change the angle and observe the sine, cosine, and tangent change with it.
