How to calculate the distance between two points?
The distance between two points in a two-dimensional coordinate system is the length of the straight line that connects the two points. It is calculated using the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.
The distance between the two points can be calculated using the following formula:
distance = √((x2 - x1)^2 + (y2 - y1)^2)
where √ represents the square root function.
For example, let's say we want to find the distance between the points (3, 4) and (8, 12).
Using the formula, distance = √((8 - 3)^2 + (12 - 4)^2) ≈ 9.43
Therefore, the distance between the two points (3, 4) and (8, 12) is approximately 9.43.
