Which of the following methods is used to find the distance between two points on a map using the scale?

The method used to find the distance between two points on a map utilizing the scale is by employing a ruler and the scale ratio. This approach allows for a precise calculation of distance by measuring the straight-line distance on the map and then converting this measurement into real-world distance using the scale provided on the map.

The scale indicates the relationship between a distance on the map and the actual distance on the ground, typically represented in a format like 1 inch equals 1 mile. By measuring the distance between the two points with a ruler, one can easily apply the scale to determine the corresponding distance in the real world. This method is reliable and commonly used in land navigation for accurate distance assessment.

Other options do not provide a direct and accurate way to measure distance on a map in the context of map reading and navigation. Relying on estimations or visual increments does not yield precise measurements. The Pythagorean theorem is useful in specific situations involving right angles, but it is not a standard method for measuring distance between two arbitrary points on a map. Finally, triangulation requires additional points of reference and calculations beyond just measuring and applying a scale, making it more complex than necessary for straightforward distance measurement on a map.
