Using Pythagoras' Theorem we can develop a formula for the distanced. Distance Formula The distance between(x1,y1)and(x2,y2)is given by: d=(x2−x1)2+(y2−y1)2\displaystyle{d}=\sqrt{{{\left({x}_{{2}}-{x}_{{1}}\right)}^{2}+{\left({y}_{{2}}-{y}_{{1}}\right...
The formula here is actually based on the Pythagorean Theorem, as you're essentially calculating one side of a triangle based on its two corner points. You'll take the differences between the x coordinates and between the y coordinates, then square those results and add them. The square root...

How the Distance Formula Works Consider a line segment identified by using the coordinates on a Cartesian plane. To determine the distance between the two coordinates, consider this segment as a segment of a triangle. The distance formula can be obtained by creating a triangle and using thePythag...
Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem, a2+b2=c2a2+b2=c2, is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c ...

By using the Pythagorean theorem, we can find the distance between two points, using the distance as the hypotenuse of a right triangle a^2 +b^2= c^2, where c is the distance you are solving for. Alternately, in a coordinate plane, we can use the formula d=sqrt((x2-x1)^2+...
To find the length ofAC, however, simple subtraction is not sufficient. TriangleABCis a right triangle withACbeing the hypotenuse. Therefore, by the Pythagorean theorem, From the Pythagorean theorem, we derive the distance formula, which is nothing more than a different format for the former. If...
triangle in Figure 1.72. Apply the square root property. Because distance is nonnegative, write only the principal square root. This result is called the distance formula. When using the distance formula, it does not matter which point you call and which you call 1x 2 , y 2 2. 1x 1...
Distance Between Two Points Formula Now, here is a derivation of the distance formula for two arbitrary points in the x-y coordinate space: Proof: Consider two points in coordinate space: A=(x1,y1) and B=(x2,y2). Draw a right triangle using A and B as two vertices: Two Points...
