| Description | Students use right triangle trigonometry and angle measurements to calculate distances using accuracy and precision. They understand the relationship between triangulation technology and other fields of study (i.e. mathematics). Accuracy of measurement in navigation depends very much on the situation. If a sailor's target is an island 200 km wide, sailing off center by 10 or 20 km is not a major problem. But, if the island were only 1 km wide, it would be missed if off just the smallest bit. Many of the measurements made while navigating involve angles, and a small error in the angle can translate to a much larger error in position when traveling long distances. |
