Students measure and analyze angles. In this trigonometry lesson plan, students measure angles and distances use non-traditional techniques. They identify the different ratios of sine, cosine and tangent.

Students evaluate the six trigonometric values of a trig function. In this trigonometry lesson, students use the Unit Circle to find the values of right triangles and their angles. They identify an angle of elevation and...

Students pretend they are hiking up a mountain. They practice making calculations on angles and elevation. They use topographic maps to estimate distances and trigonometric ratio methods.
