Week 14 – Distance Formula

This week in math we learned about the distance formula in regards to relations and how to determine the length of a line segment.

The distance formula works as follows:

This may look complicated however it is really just the Pythagorean theorem with the line segment lengths formulas plugged in.

The following diagram shows the Pythagorean theorem well:

Example: Determining the length of A (3,4) to B (8, -2)
