Distance between two points in coordinate geometry is calculated by the formula √ [ (x 2 − x 1) 2 + (y 2 − y 1) 2 ], where (x 1, y 1) and (x 2, y 2) are two points on the coordinate plane. Let us understand the formula to find the distance between two points in a two-dimensional and three-dimensional plane.
To find the distance between two points ($$x_1, y_1$$) and ($$x_2, y_2$$), all that you need to do is use the coordinates of these ordered pairs and apply the formula pictured below. The distance formula is $ \text{ Distance } = \sqrt{(x_2 -x_1)^2 + (y_2- y_1)^2} $
distance = √ a2 + b2. Imagine you know the location of two points (A and B) like here. What is the distance between them? We can run lines down from A, and along from B, to make a Right Angled Triangle. And with a little help from Pythagoras we know that: a2 + b2 = c2. Now label the coordinates of points A and B.
The formula above can be used to find the distance between two points when you know the coordinates of the points. This distance is also the length of the line segment linking the two points. This formula is simply a use of Pythagoras' Theorem .
18 wrz 2013 · Distance Between Points Formula. Rather than have to draw Pythagoras Trianges onto our graph of the two points, we can develop an Algebra Formula to save us a lot of time and work. We can subtract coordinate values to work out the “Across” and the “Up”, instead of drawing a graph and counting squares.
