Indirect Measurement Technique: Using Trigonometric Ratios
Students explore the concept of trigonometric ratios. In this trigonometric ratios lesson, students use trigonometric ratios and the angle of elevation/depression to determine the height of an object. Students use their clinometer made from a protractor, string, hex nut, and tape to determine the angle of depression/elevation of an object or building.
