Question

What is a distance ?

Answer 1

Hint:In order to answer the question, first we will discuss the definition of distance and then we will go through the conditions that occur in the concept of distance like what happen if the value of distance is negative.

Complete answer:
Distance is a numerical measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria (e.g. "two counties over"). By and large, "distance from A to B" is exchangeable with "distance from B to A". In math, a distance capacity or metric is a speculation of the idea of actual distance; it is a method of portraying what it implies for components of some space to be "near", or "far away from" one another.

In brain research and sociologies, distance is a non-mathematical estimation; Psychological distance is characterized as "the various manners by which an article may be eliminated from" the self along measurements, for example, "time, space, social distance, and hypotheticality. The distance between two points is the length of the interval joining the two points. If the two points lie on the same horizontal or same vertical line, the distance can be found by subtracting the coordinates that are not the same.

In insightful calculation, distance recipe used to discover the distance measure between two lines, the amount of the lengths of the relative multitude of sides of a polygon, edge of polygons on an arrange plane, the territory of polygons and some more. For instance, we can discover the lengths of sides of a triangle utilizing the distance equation and decide if the triangle is scalene, isosceles or symmetrical.

Note:Distance has two meanings. One is a distance magnitude and the other is a direction vector. In a magnitude the value is always positive. For example the distance from Houston to New York City is always \[1420{\text{ }}miles\] , never \[ - 1420{\text{ }}miles\] .
