What is the significance of the distance formula in geometry?

Back

The distance formula allows us to calculate the straight-line distance between two points in a coordinate plane.

Front

If the coordinates of two points are (x1, y1) and (x2, y2), what is the first step in using the distance formula?

Back

The first step is to subtract the x-coordinates and the y-coordinates: (x2 - x1) and (y2 - y1).

What is the geometric interpretation of a line segment?

Back

A line segment represents a finite distance between two points.
