Episode 6 — Analytical Geometry

Distance Formula

Learners will be able to:

• Identify the distance formula in analytical geometry as the square root of the sum of the difference in the two x values squared plus the difference in the two y values squared. • Apply the distance formula to find the distance between any two points on a straight line, using an example with given coordinates. • Simplify expressions within the square root by combining like terms and factoring out perfect squares. • Calculate the numerical value of the square root of a number using a calculator. • Express the result of a square root calculation in simplest radical form.
