Question

A scale is always chosen for the distance between two given reference points in a triangulation method because

• A. it is a convention to do so
• B. it makes calculations easy
• C. It is not possible to draw large distance on paper
• D. none of the above

Answer 1

The correct option is C

It is not possible to draw large distance on paper

Explanation of correct option:

Option (C)

1. The triangulation method is used to find large distances like the distance between stars and the Earth etc.
2. In this method, two reference points are considered to measure the distance of a distant object.
3. As the reference points are taken at a long distance from each other a scale must be chosen to get the measurement properly.
4. With the help of a scale, a large distance can be easily depicted on paper.
5. For example to draw a length of 100 km we can simply take a scale of 100 km = 1cm.
6. It will make us able to draw such a large distance with a 1cm line only.

Explanation of incorrect option:

Option (A)

1. Using a scale is only necessary when we have to represent a large distance on a paper.
2. It is not a convention that we have to follow.

Option (B)

1. Scaling means taking a large value in terms of a small and easily accessible value.
2. It does not make the calculations always easy in the case of measuring large distances using the triangulation method.

Thus, option (C) is correct.
