Substitute in the values. Distance between points 4 3 and 3 -2 is 5099. Draw a right-angled triangle with the line formed by the points the distance between the two points can be calculated by finding the horizontal x 2 - x 1 and vertical distances y 2 - y 1.
We can get above formula by simply applying Pythagoras theorem.
To find the length c take the square root of both sides of the Pythagorean Theorem. The distance between the points and is 5. Displaystyle c 2 a 2 b 2rightarrow csqrt a 2 b 2 c 2. In 3D we can find the distance between points x_1y_1z_1 and x_2y_2z_2 using the same approach.
