The Pythagorean theorem is one of the milestones in geometry that determines the relationship of the sides in square triangles, that is the relationship between the hypothenuse and the the other two sides. The example in this page is an application of the Pythagorean theorem in aviation. Watch the tutorial and then append your own example of an application of Pythagorean theorem example.
This first test and example wants to show how to compute the distance of the airplane to the airstrip knowing its altitude and ground distance to the airtrip. We can apply the Pythogorean theorem because the three vertices, airplane, airstrip, and ground position of the airplane form a square triangle with the distance being the hypothenuse.
Knowing that the relationship between the hypothenuse and the the other two sides is given by the formula
c2 = a2 + b2 ,
we can easily deduct the distance
c = √ c2
