## TRIANGULATION

**
Purpose To be able to find the distance to an object by using the triangulation method.
**

**
Goal After completing this exercise the percent of error will be less than 5%.
**

**
Constraints Pacing techniques—alignment of sighting device—scale used
**

**
Materials Protractor—sighting device—2 stakes—paper—pace knowledge—metric ruler.
**

**
Procedures
**

- 1. Using your pace, set up your base line.

*(figure available in print form)*

BASE LINE DISTANCE _____ | METERS |

- 2. Using your protractor, sighting device, and magnetic compass, determine the number of degrees to the object from the right and left side of your base line.

*(figure available in print form)*

RIGHT _____ DEGREES | LEFT _____ DEGREES |

____ SCALE: _____ cm = _____ meters

- 3. Decide on a scale to be used for distance determination.

7. Using your scale, determine the number of meters to the object. _____ meters. If possible measure the actual distance and determine the percent error.

- 4. Construct your diagram on a sheet of paper using your scaled distance for the base line and construct angles with the same degrees measured.See procedure 2 for degrees.
- 5. The location of the object is the point of intersection of lines of sight.
- 6. Measure the distance in centimeters from the vertex to the center of the base line. _____ cm
