Question

_____ is a basic geometric principle that allows finding the locations of an unknown place by knowing its distance from known places.

Hint:

Triangleation uses angles. Trilateration uses distances (think of the "lateral" movement or distance). GPS uses Trilateration!

Answer 1

Step 1: Concept
Determining an exact unknown location on Earth requires mathematical relationships based on specific reference points.

Step 2: Meaning
Global Positioning Systems (GPS) calculate your position on the ground by measuring the exact distance between your receiver and multiple satellites in space.

Step 3: Analysis

• Triangulation determines a location by measuring angles from known points.
• Trilateration determines an absolute location by measuring the exact distances (radii) from at least three known reference points, forming intersecting spheres.
• Since the definition specifically relies on "knowing its distance," the correct principle is trilateration.

Step 4: Conclusion
The geometric principle calculating location exclusively via distance is trilateration. Final Answer: Trilateration
