Answer:
We are calculating the Hypotenuse of a right triangle.
Step-by-step explanation:
Distance Formula: When working on a coordinate plane, you can always find the distance between two points (or the length of a line segment) by creating a right triangle and using the Pythagorean Theorem. Draw a right triangle such that the distance between the two points is the hypotenuse.
Hence, When you use the distance formula, you are calculating the length of the Hypotenuse of a right triangle.
