Key concepts students will learn:

  • The distance between two points can be found by drawing a right triangle and using the Pythagorean theorem.

  • The general distance formula is d = √ (x₂ - x₁)² + (y₂ - y₁)² , where d is the distance between the points (x₁, y₁) and (x₂, y₂).

  • When using the distance formula, be careful to correctly substitute the values and remember that subtracting a negative number is the same as adding a positive number.
