Trigonometric ratios sin cos tan.
Applying trigonometry to measure a real, visible object in the environment converts abstract ratios into a surveying tool. Students who measure real distances with trigonometry retain the triangle relationships better because they have a self-generated memory of what the ratios physically correspond to.
1. Make clinometer. 2. Measure angle to building top. 3. Measure distance. 4. Use tan formula.
